Despite Obama’s best efforts to gut the military, the US today still has enough technology and firepower to nuke every major city in China before a single Chinese missile comes close to striking the US. Half a billion Chinese would be dead before they even knew what hit them. Of course, political correctness would prevent this from ever happening though, even with a Republican president.
That being said, I pray that America would never get into a war with either China or Russia ever again. After all, the greatest enemy of America is not China (and definitely not Russia); it is with the followers of a certain notorious 7th century warlord.
Moreover, there are plenty of evangelical Christians in China, and any major war with China would result in Christians killing Christians in a massive scale. Not exactly something that I want to see.
