Putin’s War Crimes
I’m not sure I would call this a “major loss,” in that there was no doubt from the very beginning that Russia’s invasion of Ukraine constituted not one but several different war crimes. How this will play out vis-a-vis international justice actions, of course, is anyone’s guess.
Btw, the Court cannot impose the death penalty. Civilized nations everywhere long ago decided that hanging and the other forms of execution have no place in our world.
