So we keep standing by while he annihilates Ukraine and then what, start trading with Russia again next year?
If it leads to an escalated war then so be it, you can not let dictators do this, if nuclear weapons existed in 1939 would the world have sat ideally by while Hitler killed every fucking Jew he could get his hands on?
There isn't a lot of difference right about now, he is murdering innocent people while we watch on the news, trembling he may or may not press the button.
Will we still be trembling when he rolls into Finland, Georgia and whichever other country he fancies taking back into Russian hands.
