The Chicoms know that the ‘Rats have worked to screw up the economy in order to gain political power. They also know how badly socialism and communism actually works and that Obama’s socialist plans will screw up the economy even more.
The Chicoms also have an good grasp of ‘the long view’ in a way we in the West simply don’t consider, and because of this they know all things are temporary.
Especially when it comes to America’s leaders. 48 months is ‘nothing’ compared to 4,000 years of history.
The Chicoms have gradually evolved their economy to fascist from communist. We're the largest consumer of their goods and they're seriously into us due to their investment in U.S. Government bonds. Unlike Obama and his fellow communists, they understand what terrible damage he's doing to the U.S. economy, to which they are almost irrevocably attached. Hence, they're worried.
