please tell me why you think china is a national threat?

If you're asking whether China is a national threat, in all honesty, I can't answer that, since I'm not from China. However, if you're asking whether China is a threat to the US, I feel that it is. With its huge population, disciplined citizens (the Olympics just proved that to the world), organized military, and economic strength relative to the US (just consider the debt of US to China), it's not a stretch to think that China can be considered a threat to the US as the most dominant world power. That said, I could really only hope that a showdown among the world powers would never ensue, as it would only lead to a catastrophic mutually assured destruction. Stay positive and Happy myLotting!
