America's geopolitics regarding China has had bizarre side effects to say the least.

1. America's policy on the Arab spring was most likely all about spreading and showcasing democracy, with China in mind. As well intention as it was, it did not turn out to be a good thing. Today, large parts of the Middle East are in the grip of Islamists.

2. America's decision to withdraw from the Middle East and reposition forces in Asia has led to the end of Pax Americana in the Middle East, an Iran with nuclear capabilities, an Iran-Iraq alliance even (recent news), and bizarrely an Al Qaeda flag flying over the courthouse of Libya (see youtube).

3. America's civilian nuclear deal with India has only spurred Pakistan to expand its nuclear weapons arsenal, probably because Pakistan and India can't seem to trust each other.

America's thing with China may never turn out to be more than posturing and chest thumping. China seems to be interested only in making money.

The rise of Islamists, however, combined with WMDs in the hands of radicals, may actually turn out to be a threat.

See the documentary "Islam: what the West needs to know" (youtube) to understand why Islamic expansionism is dangerous.
