Divide and conquer, baby.
This is a gem:

Noam Chomsky: In other words, suppose that the parliament, instead of being an elite force, dominating the population, suppose the parliament represents popular will, say the popular will of 80 percent of Iraqis who want the occupying forces to withdraw, according to the British Ministry of Defence. Suppose that happens? Well then the occupying forces should immediately initiate withdrawal and leave it to the Iraqis. Now there's a good reason why Washington and London are not contemplating that. It has nothing to do with the fate of the Iraqis, quite the contrary. Just think for a minute. What would an independent Iraq be likely to do, an independent, more or less democratic Iraq? Think. I mean if you're going to have a Shi'ite majority. Therefore the Shi'ites will have a lot of influence in policy, probably a dominant influence. The Shi'ite population in the south, which is where most of the oil is, would much prefer warm relations to Iran over hostile relations to Iran. Furthermore they are very close relations already, the Badr brigade, which is the militia that mostly controls the south, was trained in Iran. The clerics have long-standing relations with Iran; the Ayatollah Sistani actually grew up there. Chances are pretty strong, they'll move towards a some sort of a loose Shi'ite alliance, with Iraq and Iran. Furthermore right across the border in Saudi Arabia, there's a substantial Shi'ite population, which has been bitterly oppressed by the US-backed tyranny in Saudi Arabia, the fundamentalist tyranny. Any move towards independence in Iraq is likely to increase the efforts to gain a degree of autonomy and justice. That happens to be where most of Saudi Arabia's oil is. So you can see not far in the future a loose Shi'ite alliance controlling most of the world's oil, independent of the US. Furthermore, it is beginning to turn toward the East. Iran has pretty much given up on Western Europe, it assumes that Western Europe is too cowardly to act independently of the US, well it has options. It can turn to the East. China can't be intimidated. That's why the US is so frightened of China. It cannot be intimidated. In fact, they're already establishing relations with Iran and in fact even with Saudi Arabia, both military and economic. There is an Asian energy security grid based on Asia and Russia but bringing in India, Korea and others. If Iran moves in that direction, having abandoned any hope in Europe, it can become the lynchpin of the Asian energy security grid.
