If we unilaterally confiscate all the weapons in the hands of the citizenry, it would make it more enticing. However, compared to the rest of the world, even if you have the technological ability to remove the threat of nuclear retaliation, you still have to face up to the fact that we are armed to the teeth and have generations of trained soldiers living in the rural areas. Pacifying that force would take human capital that only the Chinese would be willing to invest. However, that isn't a threat, because the Chinese, at least to date, haven't shown any willingness to pursue short term strategic gains that things like invasion forces bring you. They seem to be thinking in terms of centuries and are banking on our economic collapse from within. I think people in this country grossly underestimate the potential for a major economic correction that places our ability to maintain our current strength at risk.
