He isn't saying that a woman would not have started the war. So either he claims any woman leader would be so incompetent that Russia would lose the war, or so competent that she would win the war faster (which would according to him be a good thing).
I think he's saying that if a woman took over right now then all the Russian troops would be out by New Years and the war would be over, and he's saying that either because he's ignorant of the fact that the Russian invasion was an escalation of the Ukrainian civil war and that them pulling out wouldn't actually end it or because he knows that and doesn't care. Either way dumb.
