How can you guarantee that US troops will be able to control Chinese land before the Chinese can control US land? It is a completely hypothetical proposistion that is founded upon nothing other than patriotic conditioning. Not to mention that the Chinese have a greater number of nuclear weapons and 10 times the number of troops.....
First of all, I never said anything about the US invading China in my post, if you had more than a fifth grade level of reading comprehension you might have understood that. The main gist of my post is that China is militarily unable to invade the US and that a sufficiently belligerent move by either side, and any realistically aggressive move initiated by China would probably be started with an attack on US orbital recon assets, would likely escalate out of control. Second if you think China has more nuclear weapons than the US you are truly beyond reasoning with.
