just yesterday Putin warns other countries to stay away from this war. he is not bluffing with this. America can stop the war, there is just a price for it. Ukraine can stop the war too and well, for a price too.
Poland may try. there was news yesterday that they are going to reunite with what's left of Ukraine which could be a solution and west Ukraine can be Putin's profit for his war. this could be an alternative bargain or it could get worse when Putin takes Poland as well.
Poland would never attack Ukraine. Russian propagandists need to take their medication or drink less vodka.
Putin still has some time to leave Ukraine/Moldova voluntarily before his army is completely destroyed.
