Sanders would further a world war by pushing for peace with Putin while he is winning which means he gets what he wants and then will just treat this treaty like all the others...a break so he can build up for the next invasion. Ukraine has to be able to defend itself and push Putin back or this just all happens again in a few years and be even worse. God forbid he weakens NATO which just proliferates nuclear weapons by weakening the U.S. nuclear shield forcing European countries to get nukes themselves.
