Put Putin on trial.

In light of the recent atrocities and the apparent inability , or reluctance , of the UN to take meaningful action against Russia , there are growing calls for an international tribunal to try Putin for the crime of aggression. (Something the ICC cannot try him for without a Security Council referral , which Russia would obviously veto.)

Their aim is to try and recreate something like the Nuremberg Trials. Not sure if this is a starter or not , but there is a petition which has been launched to try and give it legs.
