History suggests this would be a bad idea. 'Rat regimes dither and appear indecisive, because they are, and thus encourage aggressors who expect the propitiation you predict. But internal politics and plain reality impel them to respond with force. Roosevelt did it in WW II, Truman did it in Korea, Kennedy did it in VietNam. If it came to pass, Clinton would do it in the Straits of Taiwan.
I hope you are right, but the last democrat to "do it" was Kennedy and he failed to press on to victory. As the current crop of (D) presidential hopefuls shows, that sort of democrat is near extinction. A rat prez like The Beast, put in power by the radical Left, I think will fold in the face of aggression in the tradition of Saint Jimmy Good.
