On Feb. 24, 2022, Russian fighter jets and ground troops crossed Ukraine’s border, starting an unprovoked war that’s lasted for two years, with no end in sight.
The war is part of Russian President Vladimir Putin’s effort to restore what he sees as Russia’s rightful place among the world’s great powers. He views the prospect of Ukraine joining NATO—a military alliance of 31 European and North American countries, including the United States—as a threat. And he insists that Ukraine is culturally and historically a part of Russia.
But Putin underestimated his foe. Ukraine’s army, with money and arms from the U.S. and Europe, repelled Russia’s effort to seize the capital, Kyiv, and by late 2022, had reclaimed half of the territory Russia had taken in eastern Ukraine.
“The Ukrainians’ resilience and determination to fight for their own survival is the most amazing thing about what’s happened,” says Graham Allison, a national security expert at Harvard University.
Recently, though, Russia has notched some victories. While Europe is still supplying cash and weapons to Ukraine, the U.S. Congress has for months deadlocked on continuing its support. That weakening of will may be what Putin is counting on, Allison says.
“Ukraine has been able to sustain this fight because the U.S. and the Europeans have provided arms and the financing for its basic government,” says Allison. Without further support, “Ukraine’s position becomes intolerable.”
