Will Vladimir Putin ever stand trial for war crimes?

President Biden sounded solemn after he saw images of the killings of Ukrainian civilians by Vladimir Putin's Russian troops in the town of Bucha, many shot at close range; their hands bound; and piled into shallow mass graves.

"I think it is a war crime," the president told reporters. "He should be held accountable."

But does any threat of war crimes trials deter Putin, or his Russian troops, from acts of savagery? Dozens more people died just yesterday in a Russian attack on a train station in Kramatorsk.
