China can also disrupt the US from Central and S. America where it's been active for many years, and I believe giving clandestine support to the triads which are heavily involved in human/drug trafficking through Mexico. Look, anything to fuck with America, it's all cumulative. And their cyberwar abilities are as good as it gets. I don't know if we'll ever get in a shooting war with China but I do believe they could--if not aggressively checked on all fronts, and if met with weakness and appeasement on the part of our leaders--reduce the United States to a second or even third-rate power. And that may indeed be their objective.
