Yes, I agree. My point is primarily that it is incorrect to say that his actions have an excuse, especially the hypothetical action of launching the first offensive nuke since the two in August 1945. (Secondarily, stating that he has an excuse is the first step to excusing him.) Nuclear powers collectively agree, and have for decades: the only excuse for launching a nuke at your adversary is them doing it first.

(As for elections, history has shown that there is no excuse for outright cancelling them; that is an autocratic ploy to become a despot.)
