Via Hitchens:

(1) The overthrow of Talibanism and Baathism, and the exposure of many highly suggestive links between the two elements of this Hitler-Stalin pact. Abu Musab al Zarqawi, who moved from Afghanistan to Iraq before the coalition intervention, has even gone to the trouble of naming his organization al Qaeda in Mesopotamia.

(2) The subsequent capitulation of Qaddafi's Libya in point of weapons of mass destruction--a capitulation that was offered not to Kofi Annan or the E.U. but to Blair and Bush.

(3) The consequent unmasking of the A.Q. Khan network for the illicit transfer of nuclear technology to Libya, Iran, and North Korea.

(4) The agreement by the United Nations that its own reform is necessary and overdue, and the unmasking of a quasi-criminal network within its elite.

(5) The craven admission by President Chirac and Chancellor Schröder, when confronted with irrefutable evidence of cheating and concealment, respecting solemn treaties, on the part of Iran, that not even this will alter their commitment to neutralism. (One had already suspected as much in the Iraqi case.)

(6) The ability to certify Iraq as actually disarmed, rather than accept the word of a psychopathic autocrat.

(7) The immense gains made by the largest stateless minority in the region--the Kurds--and the spread of this example to other states.

(8) The related encouragement of democratic and civil society movements in Egypt, Syria, and most notably Lebanon, which has regained a version of its autonomy.

(9) The violent and ignominious death of thousands of bin Ladenist infiltrators into Iraq and Afghanistan, and the real prospect of greatly enlarging this number.

(10) The training and hardening of many thousands of American servicemen and women in a battle against the forces of nihilism and absolutism, which training and hardening will surely be of great use in future combat.

(6) of course was the justification given by the powers that took us to war. I've argued that it is sufficient in and of itself, but that the case was overwhelming when combined with the need to overthrow a despicable regime like Saddam's (1). The others are all beneficial by-products.

But where is it all going...or rather:

The peaceniks love to ask: When and where will it all end? The answer is easy: It will end with the surrender or defeat of one of the contending parties. Should I add that I am certain which party that ought to be? Defeat is just about imaginable, though the mathematics and the algebra tell heavily against the holy warriors. Surrender to such a foe, after only four years of combat, is not even worthy of consideration.
