Explainers

  • The sprawling U.S. water system is central to the nation’s economy, but chronic underinvestment, increasing demand, and the consequences of climate change have revealed the system’s weaknesses.  
  • Differences over Taiwan’s status have fueled rising tensions between the island and the mainland. Taiwan has the potential to be a flash point in U.S.-China relations.
  • Tens of thousands of unaccompanied children have been arriving at the U.S.-Mexico border each year, sparking debate over how to respond. How is the Joe Biden administration handling it?
  • Venezuela’s descent into economic and political chaos in recent years is a cautionary tale of the dangerous influence that resource wealth can have on developing countries.
  • Russia’s threat to deploy tactical nuclear weapons in Belarus has raised the specter of a new nuclear standoff with the United States and its allies in Europe. It also draws new attention to how such arms are deployed in NATO states.
  • The meeting of Russian President Vladimir Putin and Chinese leader Xi Jinping in Moscow helped both give the impression of a united front, but underlying tensions were also discernible.
  • The mass protests that have rocked Peru since December threaten to upend regional supply chains, intensify migration flows, and strain Lima’s bilateral relations.  
  • The Biden administration’s proposed immigration policy aims to curb migrant flows to the United States amid record border crossings. What will it do, and how does it compare to the Trump years?
  • Turkey’s presidential candidates officially kick-off their campaigns ahead of May elections; Russia begins its term as president of the UN Security Council; and Walt Disney World wraps up its fiftieth anniversary celebration amid legal disputes with the Florida state government.
  • As rising global temperatures thaw the ice at the North Pole of the planet, competition between nuclear-powered states threatens to heat up the Arctic Circle even further. An increasingly minable Arctic, which contains vast natural resources, has piqued the economic interests of oil-hungry great powers, even as the warmer climate jeopardizes Indigenous tribes. Here’s how the Arctic could become the next frontier of great-power competition.
  • Paul Scharre, the vice president and director of Studies at the Center for a New American Security, sits down with James M. Lindsay to discuss how artificial intelligence is reshaping great power competition and intensifying the geopolitical rivalry between China and the United States.
  • The Center for Preventive Action’s Global Conflict Tracker is an interactive guide to ongoing conflicts around the world of concern to the United States.
  • Most countries still have laws that make it harder for women to work than men. This inequality shortchanges not only women but also entire economies.
  • Japan's constitutional debate is about not simply the document's past but also the nation's ability to respond to twenty-first-century challenges.
  • This interactive examines how nationwide bans on menthol cigarettes and flavored cigars, as proposed by the Biden administration on April 28, 2022, could help shrink the racial gap on U.S. lung cancer death rates.
  • China’s political system is complicated, and there’s a lot of contradictory information out there. Is China a communist country? Is it democratic, as its own government insists? And what does “freedom” mean to Chinese citizens? Ian Johnson, CFR’s senior fellow for China studies, answers these questions and more.
  • Since the creation of Bitcoin in 2009, cryptocurrencies have exploded in popularity and accrued over $1 trillion in collective value. But market volatility in 2022 threatened the crypto ecosystem—after peaking at over $68,000 in November 2021, the price of Bitcoin fell to under $17,000 twelve months later. This instability has brought new scrutiny to the industry and the countries that have embraced Bitcoin as currency: El Salvador and the Central African Republic. Financial regulators are now calling for more crypto oversight, but global efforts to regulate the industry have stalled. Given this simultaneous rise in global popularity and concern, what lies ahead for digital currency and the future of finance?
  • The world is running out of time to avoid the worst consequences of climate change. With the 2015 Paris Agreement, countries set a goal of limiting global warming to 1.5°C (2.7°F) compared to 150 years ago. However, the planet is on track to pass 1.5°C by the end of this decade, which would lead to higher sea levels, hotter heat waves, and deadlier natural disasters. But countries can work to prevent those and even worse dangers by sticking to their climate pledges and limiting just how much the world overshoots its Paris Agreement goal.
  • After years of tension, relations between the United States and Venezuela appear to be headed in a new direction. The Joe Biden administration has temporarily rolled back some U.S. sanctions on Venezuela’s oil industry in an effort to curb energy prices as well as help the Venezuelan people. But the extent of this détente hinges on Venezuelan President Nicolás Maduro. What’s in store for bilateral relations?
  • The United States and China have one of the world’s most important and complex bilateral relationships. Since 1949, the countries have experienced periods of both tension and cooperation over issues including trade, climate change, and Taiwan.
  • Negotiations between the United States and North Korea have proceeded in fits and starts for decades. But they have failed to halt the advance of North Korea’s nuclear and missile programs.
  • Since India’s independence, ties with the United States have weathered Cold War–era distrust and estrangement over India’s nuclear program. Relations have warmed in recent years and cooperation has strengthened across a range of economic and political areas.
  • The Kurds are one of the world’s largest peoples without a state, making up sizable minorities in Iran, Iraq, Syria, and Turkey. Their century-old fight for rights, autonomy, and even an independent Kurdistan has been marked by marginalization and persecution.
