Why does every political topic have to turn into China v USA WWIII
Because it's a forum full of 15-year-old boys who think that China is like this arch-nemesis of freedom and is this tyrannical country, even though one of the biggest things Obama has done during his time as president is to improve our political ties.
I would also like to point out that China couldn't just cut off their economical ties with us: They are a heavy exporting country that relies on purchases from around the world. That said, what would happen if they didn't export for say, 20 years (WWIII time estimate on my part?) I can fairly comfortably assume their economy would be in shambles.
