Doesn't mean we have to go through a all out war. At least mobilize troops towards that area. See the reaction of other countries, then move from there. If we sent troops there, and china did nothing then of course go in. But if the were setting up for attack too, then back off. At least we did something. Obviously china wanted nothing to do with NK or they would of spoke up when Bush made that hollow *** threat to do something to NK if they kept testing nukes. But china kept quite.
And yes they make alot of our products. But we buy the products, so they need us just as much as we need them.
