I think China is in a better position to put pressure on US, than we them. Just for starters, they own about 71% of all our home mortgages, with Japan owning about 21%.
All the money our government is borrowing right now is from China. If they quit buying our bonds and such, our economy will likely crash and Barack, the Congress and the Senate that sold us out, all know that.
Do I like it, no I don't, but it is a reality, that we have lost our influence with this "preemptive strike" mentality, and nation building government.
I would also have to agree with all BBF said, with the possible exception of Israel hitting Iran's nuclear facilities. I feel Israel has no other choice in that matter.
