Could China kill the US Dollar?

For the last few years, increasing numbers of commentators, including Max Keiser, have been predicting the collapse of the US dollar, a collapse that could be closer than you think. America currently faces a very real, impending threat -- China. China accounts for more global trade than anyone else on the planet, and most of that trade happens in US dollars keeping demand for the dollar high and overseas trade at low costs. Not only this, but China holds around 1.3 trillion dollars of US debt. A debt accumulated by China's stockpile of dollars from international trade which they lend back to the US at ridiculously low interest rates. But what happens if they stop playing the game? Well, in some respects they already have.
