China is finally rising from its slumber. It's buying all the oil, steel, and concrete it can get its hands on to build, build, build. It will be the only thing approaching superpower status to challenge US dominance. If our economies are intertwined, I would expect our relationship with China to be valued by the leaders of both countries. The odds of World War V will be lower - allowing us to finish WW IV (WOT) properly.
An eventuality which is contradicted by most of human history, but hey!! Enjoy the thought while you can...
