Iraq hasn't even begun (LATimes)
In an article for the Web magazine Open Democracy, Middle East specialist Fred Halliday spells out some regional consequences. Besides the effective destruction of the Iraqi state, these include the revitalizing of militant Islamism and enhancement of the international appeal of the Al Qaeda brand; the eruption, for the first time in modern history, of internecine war between Sunni and Shiite, "a trend that reverberates in other states of mixed confessional composition"; the alienation of most sectors of Turkish politics from the West and the stimulation of authoritarian nationalism there; the strengthening of a nuclear-hungry Iran; and a new regional rivalry pitting the Islamic Republic of Iran and its allies, including Syria, Hezbollah and Hamas, against Saudi Arabia, Egypt and Jordan.

For the United States, the world is now, as a result of the Iraq war, a more dangerous place. At the end of 2002, what is sometimes tagged "Al Qaeda Central" in Afghanistan had been virtually destroyed, and there was no Al Qaeda in Iraq. In 2007, there is an Al Qaeda in Iraq, parts of the old Al Qaeda are creeping back into Afghanistan and there are Al Qaeda emulators spawning elsewhere, notably in Europe.
