So you mean we should be happy with peace on russian terms and rewarding them for invading their neighbour? Russia is very much weakened and probably would like this though.
Wait, is Russia so weakened that it's unable to win this war or is it so strong that if it wins, Europe and eventually even the USA would be next? Pick one, you can't have both.
I personally am not afraid of russia successfully invading my country, especially considering how much men and equipment they lost in Ukraine. But if the war in Ukraine would end on Russian terms, they might get more stupid ideas later after rebuilding their military.
