President Donald J. Trump has promised sweeping changes to U.S. foreign policy. Trump vowed to reverse many of President Barack Obama’s signature achievements, including the Asia-Pacific Trans-Pacific Partnership (TPP) trade deal, the landmark climate change accord signed by 197 nations in Paris, and an agreement with Iran to restrict its nuclear program. He promised to continue and intensify border enforcement policies undertaken under Presidents George W. Bush and Obama and finish building a wall on the U.S. border with Mexico. His energy policy would represent a break with Obama’s push for a less carbon-intensive economy, while his willingness to place a U.S. embassy in Jerusalem could send shockwaves through an already volatile region.
In many of these areas, the president holds significant executive authority and can unilaterally enact change. In some instances, however, Trump will be constrained by treaty obligations, the prerogatives of the U.S. Congress, the requirements of the federal rulemaking process, or rulings by the U.S. Supreme Court:
Upending Trade Policy
Trump made trade policy a centerpiece of his campaign, promising to upend decades of bipartisan consensus on the desirability of low tariffs and deeper cross-border integration. While many of Trump’s proposals have not yet been legally tested, experts say that U.S. law gives the president broad powers to unilaterally raise tariffs and modify existing trade agreements.
Trump has various options for reorienting future U.S. trade priorities, including favoring bilateral agreements over regional multicountry deals. He signed an executive order withdrawing the United States from the Trans-Pacific Partnership (TPP), negotiated by the Obama administration with eleven other Pacific Rim countries, immediately after taking office. Meanwhile, the White House press secretary, Sean Spicer, said that “multinational agreements [are] not in our best interest,” calling into question a potential U.S.-European Union trade deal and World Trade Organization (WTO) negotiations on trade in services and environmental goods.
Trump has been a fierce critic of the North American Free Trade Agreement, or NAFTA, between Canada, Mexico, and the United States. He promised to notify NAFTA members of his intention to either renegotiate or withdraw from the deal, and Commerce Secretary Wilbur Ross said at his Senate confirmation hearing that NAFTA would be “logically the first thing for us to deal with.” Under NAFTA’s provisions, the president can unilaterally withdraw the United States from the accord, as well as raise tariffs on Canada and Mexico to pre-deal levels. Trump can also reopen negotiations, but major amendments to NAFTA—for instance, abolishing the controversial investor-state dispute settlement (ISDS) mechanism—would likely require congressional approval.
The incoming administration has pledged to crack down on what it considers unfair trade practices by foreign competitors, especially China.
The incoming administration has also pledged to crack down on what it considers unfair trade practices by foreign competitors, especially China. One option is for the U.S. trade representative to more aggressively bring complaints against China at the WTO. But those challenges take time, while the Department of Commerce and the U.S. International Trade Commission have wide latitude to apply retaliatory duties and tariffs on imports that they find have received state subsidies (they already do so on many Chinese goods). Trump’s Treasury Department may also decide to label China a “currency manipulator,” a move that experts say would be largely symbolic.
Finally, Trump has repeatedly threatened to apply punitive tariffs on companies that outsource jobs. Experts say that a suite of existing laws could permit him to do so for reasons of “national emergency” or national security, categories open to broad interpretation.
Strengthening Immigration and Border Enforcement
Southern border wall. As a presidential candidate, Trump stated that on day one of his presidency he would begin work on an “impenetrable physical wall on the southern border,” and that Mexico would pay for it. The Department of Homeland Security (DHS), which, under the direction of the president, enforces federal immigration laws and controls U.S. borders, builds barriers and roads to deter illegal immigration. President George W. Bush enacted legislation in his second term requiring DHS to build at least seven hundred miles of reinforced fencing along the roughly two-thousand-mile border with Mexico. His administration built a majority of this stretch. While the Obama administration continued to add fencing during its first term, it did not fulfill the statutory requirement.
In his first week in office, Trump issued an executive order directing available federal funds to the wall’s construction and ordering the preparation of congressional budget requests for future years. He has pledged to make Mexico reimburse the U.S. government for the costs of completing the wall, which DHS estimated could be more than $21 billion. Trump says several measures could persuade the Mexican government to repay this money, such as imposing tariffs on Mexican imports, canceling Mexican nationals’ visas, or prohibiting unauthorized immigrants from wiring funds to Mexico. Some legal experts dispute whether Trump has the authority to restrict remittance payments.
Sanctuary cities. Trump also pledged during his presidential campaign to cancel “all federal funding to sanctuary cities,” referring to the hundreds of jurisdictions that limit their cooperation with federal immigration agencies. Critics say that sanctuary cities undermine law enforcement and encourage illegal immigration. Supporters say that unauthorized immigrants are more likely to cooperate with local police if they do not fear deportation.
Trump issued an additional executive order on January 25 instructing federal officials to designate sanctuary jurisdictions ineligible to receive federal grants. Legal scholars are skeptical that the president has the constitutional authority to withhold all federal funds, citing several Supreme Court rulings that limited what conditions the federal government can impose on funding to cities and states. Members of Congress could require recipient jurisdictions to cooperate with federal authorities; several have introduced measures in recent years that are intended to prohibit sanctuary jurisdictions from receiving certain federal funds.
Trump says several measures could persuade the Mexican government to pay, such as imposing tariffs on Mexican imports, canceling Mexican nationals’ visas, or prohibiting unauthorized immigrants from wiring funds to Mexico.
Deportations. Trump vowed during his campaign to begin the removal of “two million criminal illegal immigrants,” as well as to cancel the issuance of visas to nationals of countries that “won’t take them back.” DHS estimated in a justification budget report for FY 2013 that some 1.9 million noncitizen immigrants have been convicted of crimes, but that total included legal immigrants. Trump’s promise to deport “criminal illegal aliens” may resemble actions Obama took during his first term, when the number of annual deportations increased, though Trump could broaden the priorities of immigration officials to include unauthorized immigrants who have been charged with crimes, even if they have not been convicted.
Trump’s executive order on interior enforcement prioritized the removal of unauthorized immigrants accused of committing criminal acts and called for hiring ten thousand new immigration officers. In February, DHS released two memorandums authorizing executive agencies to deport unauthorized immigrants without first giving them a hearing, build new detention facilities, and empower state and local law enforcement to enforce federal immigration law, among other directives.
Trump also pledged before the election to “immediately terminate President Obama’s two illegal executive amnesties,” referring to the Deferred Action for Childhood Arrivals (DACA) and Deferred Action for Parents of Americans and Lawful Permanent Residents (DAPA) programs. The DHS memos state that Obama’s executive orders on DACA and DAPA would not be immediately rescinded, saying instead that the department would provide guidance at a future date.
Travel ban. Another of Trump’s campaign pledges was to “suspend immigration from terror-prone regions where vetting cannot safely occur.” Under the Immigration and Nationality Act of 1952 (INA), the president has the authority to ban the entry “of any aliens or of any class of aliens” into the country for as long as he deems necessary if he finds their entry would be “detrimental to the interests of the United States.” A 1965 law amended the INA to prohibit discrimination against visa applicants based on “race, sex, nationality, place of birth, or place of residence.” Presidents Obama, George W. Bush, Bill Clinton, and Ronald Reagan all issued multiple proclamations during their tenures that banned the entry of specific groups, either from a particular country or, more broadly, for involvement in criminal or terrorist activities, including corruption and human rights abuses.
In late January, Trump signed an executive order suspending refugee admissions for 120 days, capping the number of refugees that would be allowed into the United States in 2017 at fifty thousand, and banning travelers from seven Muslim-majority countries—Iran, Iraq, Libya, Somalia, Sudan, Syria, and Yemen—for at least ninety days. The order blocked the entry of Syrian refugees indefinitely. Trump instructed immigration agencies to prioritize the refugee applications of persecuted religious minorities. However, days after the order was issued, a federal court in Seattle issued a nationwide injunction temporarily blocking officials from carrying out the order, questioning its constitutionality.
On March 6, Trump issued a revised executive order that was crafted to survive legal challenges like those that faced the original one and prevent the bureaucratic confusion that followed its implementation. The new order, set to go into effect ten days later, drops Iraqis from the list of banned nationalities and removes the indefinite ban on Syrian refugees. It also omits preferential status for religious minorities and exempts current visa holders and permanent residents.
Reversing Obama on Energy and Climate
As a candidate, Trump vowed to reverse President Obama’s efforts to move the U.S. economy away from carbon-intensive fuels. Since the election, Trump has moderated some of his views, but retains the power to undo, or at least severely hobble, many of the Obama administration’s signature climate and energy policies.
Trump originally pledged to “cancel” the 2015 Paris Agreement, an accord among 197 countries to voluntarily reduce their climate change emissions, though he later said he has “an open mind” on the deal. According to the agreement, countries must wait four years before withdrawing from it. However, legal analysts say that Trump could speed that process to just one year by removing the United States from the 1992 treaty governing global climate talks, which the president has the authority to do without congressional backing. He can also cancel the remaining $2 billion of the U.S. pledge of $3 billion to the UN’s Green Climate Fund.
Trump retains the power to undo, or at least severely hobble, many of the Obama administration’s signature climate and energy policies.
Experts say that Trump could also effectively end U.S. participation in the deal by undermining the Clean Power Plan (CPP), the centerpiece of Obama’s promise at Paris to reduce U.S. carbon output.
The CPP is not legislation but rather a set of Environmental Protection Agency (EPA) regulations setting emissions reduction requirements for each state. Currently, the CPP is on hold due to a court challenge arguing that the EPA is overstepping its constitutional bounds. While the Trump administration could decline to continue defending the CPP in court, legal commentators disagree over how much latitude the president has to unilaterally abandon it. Some opponents argue that an executive order directing the EPA to stop enforcement of the plan would effectively kill it, while others say that the administration would have to proceed through the time-consuming federal rulemaking process to change the CPP. An act of Congress could also override EPA rules.
Trump has also promised to roll back numerous other Obama-era regulations on energy and the environment. He immediately issued executive orders to revive the Keystone XL and Dakota Access (DAPL) pipelines and streamline the environmental review process for other such projects. Within a month of his inauguration, he directed the Army Corps of Engineers to grant the final approval for DAPL, allowing construction to proceed. In addition, he could use his executive authority to reverse a ban on oil drilling in the Arctic and lift a moratorium on selling coal-mining rights for federally owned land. He could weaken the stricter vehicle fuel-efficiency standards introduced by Obama’s EPA and also reduce federal subsidies for clean-technology development.
Reopening the Iran Deal
“My number-one priority is to dismantle the disastrous deal with Iran,” Trump told the American Israel Public Affairs Committee during the primary campaign, referring to Iran’s agreement with six major powers to restrict its nuclear program in exchange for sanctions relief. Elsewhere on the campaign trail he said he would renegotiate it to secure better terms. Members of the incoming administration have sent mixed messages on what course they would recommend.
The agreement, formally known as the Joint Comprehensive Plan of Action (JCPOA), reached the one-year anniversary of its implementation just days before Trump’s inauguration. There have been hiccups along the way. Iran has committed fouls, twice exceeding permissible production levels of heavy water. Meanwhile, Iran attributes its still-stagnant economy to the United States moving too slowly on its sanctions-relief obligations. International banks have yet to integrate Iran back into the global economy and businesses have been slow to invest in the country, fearing that they will run afoul of U.S. Treasury regulations or that lifted sanctions might be reimposed. Still, even as Iran remains a U.S. adversary in much of the Middle East, many nonproliferation experts consider the JCPOA a success thus far. Iran’s nuclear program is more transparent than before.
Trump could unilaterally withdraw the United States from the agreement, in which case Iran would have to decide whether to continue to fulfill its obligations. He could also likely unilaterally reimpose UN sanctions if he were to allege significant Iranian violations at the Security Council.
Trump could unilaterally withdraw the United States from the agreement, in which case Iran would have to decide whether to continue to fulfill its obligations.
But the new president has other means of jeopardizing the agreement. To fulfill U.S. commitments, Trump must periodically waive secondary sanctions (that is, those targeting non-U.S. entities; the primary embargo still stands, blocking U.S. entities from transacting with Iran). He could decline to issue those waivers. Likewise, he could sign into law new sanctions passed by Congress, or impose others by executive order. Though the sanctions might claim to cover Iran’s ballistic-missile program or regional adventurism rather than the nuclear file, Iran might view them as a violation of U.S. commitments under the JCPOA.
Trump could also seek to renegotiate the agreement to extend its restrictions on uranium enrichment beyond their fifteen-year expiration or cover ballistic missiles, for example. But Iran’s president, Hassan Rouhani, who faces a difficult reelection campaign this year, said the agreement cannot be renegotiated. “JCPOA is a finished deal,” his deputy foreign minister said. The other parties to the JCPOA are content with the status quo. If the agreement were to fall apart because of U.S. moves, they would be unlikely to reinstate sanctions of their own.
Moving the U.S. Embassy to Jerusalem
One of the most potentially incendiary campaign promises that Trump could enact right away is to move the U.S. embassy in Israel from Tel Aviv to Jerusalem. Though moving all the embassy’s operations would be cumbersome, Trump could fulfill his pledge simply by having the U.S. ambassador establish his office or residence at the existing US. Consulate General in Jerusalem. The ambassador designate, bankruptcy lawyer David Friedman, said he looks forward to serving from Jerusalem, but the White House has since indicated that a decision is not imminent.
Israel considers Jerusalem its “eternal, undivided capital,” and its prime minister, Knesset (parliament), and Supreme Court sit in west Jerusalem. Palestinians claim east Jerusalem, which Israel annexed after capturing it from Jordan in 1967, as the future capital of their state. U.S. presidents since Harry Truman have held that the disposition of Jerusalem must be determined in negotiations between the parties. The Oslo Accords, agreed to by Israel and the Palestine Liberation Organization (PLO) in 1993, deferred a resolution of the city’s status to an eventual final agreement.
U.S. presidents since Harry Truman have held that the disposition of Jerusalem must be determined in negotiations between the parties.
Congress required the U.S. embassy’s relocation in a 1995 law, but allowed for the president to waive this requirement every six months “to protect the national security interests of the United States.” (Attempts to legislate U.S. policy on Jerusalem have spurred constitutional debates over executive versus congressional authority in setting foreign policy.) Presidents Clinton, Bush, and Obama have done so ever since. If Trump decides to follow through with moving the embassy, he would only need to revoke the current waiver or decline to issue a new one. (Obama last signed a waiver on December 1.)
Proponents of the status quo say an embassy move could diminish Palestinians’ faith in negotiations, undermine Washington’s claim to being a fair broker, and signal that the holy city will remain beyond Muslim control. That could spur demonstrations or violence in Jerusalem or across the Middle East; rupture Israeli relations with Egypt, Jordan, and Arab Gulf states; and endanger U.S. diplomatic facilities. Palestinian leaders have said they would withdraw recognition of Israel and move to join UN institutions like its nuclear watchdog or the World Trade Organization. Trump would then, by law, have to pull U.S. funding—and thus influence—from them.
Advocates of relocation say the fallout could be contained, since west Jerusalem, the Jewish-majority portion of the city that lies within Israel’s pre-1967 borders, is presumed to remain in Israel under a two-state solution. Washington could indicate that its move is not meant to prejudice future negotiations with respect to Israeli borders, a future Palestinian capital, or the disposition of holy sites, but that would not likely placate Palestinians.
