Recent Developments
The conflict in eastern Ukraine has transitioned to a stalemate after it first erupted in early 2014, but shelling and skirmishes still occur regularly, including an escalation in violence in the spring of 2018.
Since taking office, the Donald J. Trump administration has continued to pressure Russia over its involvement eastern Ukraine. In January 2018, the United States imposed new sanctions on twenty-one individuals and nine companies linked to the conflict. In March 2018, the State Department approved the sale of anti-tank weapons to Ukraine, the first sale of lethal weaponry since the conflict began, and in July 2018 the Department of Defense announced an additional $200 million in defensive aid to Ukraine, bringing the total amount of aid provided since 2014 to $1 billion.
In October 2018, Ukraine joined the United States and seven other North Atlantic Treaty Organization (NATO) countries in a series of large-scale air exercises in western Ukraine. The exercises came after Russia held its annual military exercises in September 2018, the largest since the fall of the Soviet Union.
Background
The crisis in Ukraine began with protests in the capital city of Kiev in November 2013 against Ukrainian President Viktor Yanukovych’s decision to reject a deal for greater economic integration with the European Union. After a violent crackdown by state security forces unintentionally drew an even greater number of protesters and escalated the conflict, President Yanukovych fled the country in February 2014.
In March 2014, Russian troops took control of Ukraine’s Crimean region, before formally annexing the peninsula after Crimeans voted to join the Russian Federation in a disputed local referendum. Russian President Vladimir Putin cited the need to protect the rights of Russian citizens and Russian speakers in Crimea and southeast Ukraine. The crisis heightened ethnic divisions, and two months later pro-Russian separatists in the Donetsk and Luhansk regions of eastern Ukraine held a referendum to declare independence from Ukraine.
Violence in eastern Ukraine between Russian-backed separatist forces and the Ukrainian military has by conservative estimates killed more than 10,300 people and injured nearly 24,000 since April 2014. Although Moscow has denied its involvement, Ukraine and NATO have reported the buildup of Russian troops and military equipment near Donetsk and Russian cross-border shelling.
In July 2014, the situation in Ukraine escalated into an international crisis and put the United States and the European Union (EU) at odds with Russia when a Malaysian Airlines flight was shot down over Ukrainian airspace, killing all 298 onboard. Dutch air accident investigators concluded in October 2015 that the plane had been downed by a Russian-built surface-to-air missile. In September 2016, investigators said that the missile system was provided by Russia, determining it was moved into eastern Ukraine and then back to Russian territory following the downing of the airplane.
Since February 2015, France, Germany, Russia, and Ukraine have attempted to broker a cessation in violence through the Minsk Accords. The agreement includes provisions for a cease-fire, withdrawal of heavy weaponry, and full Ukrainian government control throughout the conflict zone. However, efforts to reach a diplomatic settlement and satisfactory resolution have been unsuccessful.
In April 2016, NATO announced that the alliance would deploy four battalions to Eastern Europe, rotating troops through Estonia, Latvia, Lithuania, and Poland to deter possible future Russian aggression elsewhere in Europe, particularly in the Baltics. These battalions were joined by two U.S. Army tank brigades, deployed to Poland in September 2017 to further bolster the alliance’s deterrence presence.
Ukraine has been the target of a number of cyberattacks since the conflict started in 2014. In December 2015, more than 225,000 people lost power across Ukraine in an attack, and in December 2016 parts of Kiev experienced another power blackout following a similar attack targeting a Ukrainian utility company. In June 2017, government and business computer systems in Ukraine were hit by the NotPetya cyberattack; the crippling attack, attributed to Russia, spread to computer systems worldwide and caused billions of dollars in damages.
Concerns
The conflict in Ukraine risks further deterioration of U.S.-Russia relations and greater escalation if Russia expands its presence in Ukraine or into NATO countries. Russia’s actions have raised wider concerns about its intentions elsewhere in Eastern Europe, and a Russian incursion into a NATO country would solicit a response from the United States as a NATO ally. The conflict has heightened tensions in Russia’s relations with both the United States and Europe, complicating the prospects for cooperation elsewhere including on issues of terrorism, arms control, and a political solution in Syria.
