Only temporarily. Once the communists sink into the hell of their own making, they will still be jealous of the Free and will wage war, only now they will be vessel states of china and we will be fighting both on our own soil.
The communists will have no military. They will be easily taken over by China and become a vassal state with no autonomy at all.
Fighting China seems inevitable.
The fact that you think we need those on the left to win is amusing.
