It was the harshest condemnation of Putin’s actions from any US official since the war in Ukraine began three weeks ago. Previously, Biden had stopped short of labeling atrocities being documented on the ground in Ukraine as “war crimes,” citing ongoing international and US investigations.
But on Wednesday, speaking with reporters at an unrelated event, Biden affixed the designation on the Russian leader.
“I think he is a war criminal,” Biden said after remarks at the White House.
The shift from the administration’s previous stance came after an emotional address to Congress from Ukrainian President Volodymyr Zelensky, who aired a video showing Ukrainians suffering amid Russia’s onslaught. Zelensky asked American lawmakers and Biden for more help defending itself, including a no-fly zone and fighter jets.
Biden responded in his own address a few hours later, laying out new American military assistance to Ukraine — including anti-aircraft and anti-armor systems, weapons and drones — but stopping short of acceding to Zelensky’s requests.
Still, Biden acknowledged the horrors transpiring on the ground.
“We saw reports that Russian forces were holding hundreds of doctors and patients hostage in the largest hospital in Mariupol,” Biden said. “These are atrocities. They’re an outrage to the world. And the world is united in our support for Ukraine and our determination to make Putin pay a very heavy price.”
It wasn’t until a few hours after that that Biden responded to a question about Putin being a war criminal. Biden initially said “no,” but immediately returned to a group of reporters to clarify what had been asked. When asked again whether Putin was a war criminal, he answered in the affirmative.
In Poland last week, Vice President Kamala Harris called for international investigations into war crimes, and made clear she believed atrocities were underway. She said the intentional targeting of civilians would constitute war crimes.
After Biden delivered his assessment, the White House said the administration’s investigation into war crimes would continue.
“The President’s remarks speak for themselves,” press secretary Jen Psaki said. She said Biden was “speaking from the heart.”
While the term “war crimes” is often used colloquially — as Biden appeared to be doing Wednesday — they do have a legal definition that could be used in potential prosecution. That includes in the Geneva Convention, which specifies intentional targeting of civilians as a war crime.
Yet in order to prosecute a war crime, solid evidence is required. And for Russian officials to be held accountable, they would need to travel outside of the country.
Still, an official designation of war crimes — backed up with evidence — would still present the West with a symbolic tool in framing Putin’s actions in Ukraine.
Biden has come under increasing pressure to do more to help besieged Ukrainians as Russia’s campaign intensifies. On Wednesday, a theater in Mariupol where civilians were sheltering was bombed, the latest example of Russia’s indiscriminate shelling.
The pressure was only likely to increase after Zelensky’s dramatic appeal to lawmakers for more help. He compared what is happening in Ukraine to Pearl Harbor and September 11, and said “we need you right now” to offer more support.
Biden watched the address from the library of his private residence, and later called it a “convincing” and “significant” speech.
“Putin is inflicting appalling, appalling devastation and horror on Ukraine, bombing apartment buildings, maternity wards, hospitals,” he said afterward. “I mean, it’s godawful.”
Next week, Biden plans to travel to Brussels for an extraordinary session of NATO leaders, where he hopes to demonstrate western unity amid Russia’s aggression.
