Chinese doesn't need to use force to cripple the USA. They now have the US in an economic headlock. They can kill the US economy and US dollar by simply dumping the Trillion of so US dollars they have for the Euro. The USA would never recover.
exactly, military force is not the only option for Chinese to invade this country. Look at the big picture right now, I have seen more and more chinese students coming to US to study, to work, to do whatever they can here. and our government embrace them with full two arms because our poor economy needs their money. Every year, the number of US visa that gives to Chinese is dramatically increasing.
Most of those chinese students choose to stay in US after they finish their study, they are hard-working, they are willing to do whayever they can get to survive in this country, and most of them succeed in melting them into the society, which means they will live here, work here, get married here and have more Chinese, or half-chinese children here.
Look at the big picture in US generation after generation, we might be having a Chinese to be our president in the future.
