Which ones?
Before you list "war crimes" look back at our last 20 years in Iraq, Afghanistan or Lybia/Syria. Civilians deaths, thermobaric bombs, cluster munitions (maybe)... when Americans or our allies kill civilians, it's a mistake... but when Putin does it.. it's a war crime.
If we demand Putin go to prison or kill him, you and our leadership fails to thing about what a man will do if he has nothing left to lose..... he has nukes.
