Like? Is anyone who starts a war a “war criminal” now?

If it’s because Russia’s killed civilians (whether intentionally or just because they didn’t care enough in pursuit of their military objectives), then, like, isn’t basically every Western leader + Biden a “war criminal”? How would you ever create a standard that could include him but not others?

And if they are all “war criminals” then why would you support one over the other? I don’t get this conversation.

And even if you had to, like, in what world would it make sense to think that Putin is worse than Netanyahu or the Western leaders who arm and support him?
