There is also a lesson to be learned here in that this morning there will be excitement and satisfaction in the palaces of Washington, Tel Aviv, Riyadh and Tehran. All of the political elites will see prospects for gain from the new fluidity. While for ordinary people in all those countries there is only the certainty of more conflict, death and economic loss, for the political elite, the arms manufacturers, the military and security services and allied interests, the hedge funds, speculators and oil companies, there are the sweet smells of cash and power.
Tehran will be pleased because the USA has just definitively lost Iraq. Iraq has a Shia majority and so naturally tends to ally with Iran. The only thing preventing that was the Arab nationalism of Saddam Hussein's Ba'ath Socialist Party. Bush and Blair were certainly fully informed that by destroying the Ba'ath system they were creating an Iranian/Iraqi nexus, but they decided that was containable. The "containment" consisted of a deliberate and profound push across the Middle East to oppose Shia influence in proxy wars everywhere.
