If you expand your view, you can see things better.
US regime is already spread too thin around the world. They can not sustain this situation for long specially since they are hemorrhaging money, in trillions. They need to reduce their costs at some point and that means abandoning some of the wars they are participating in specially when the problems pile on back home.
Also since according to all the National Security thing they release, China is on top of the lists of countries US has to declare war on, they will shift all their focus to East Asia sooner or later.
