From Victor Davis Hanson at National Review Online:
The truth about Iraq is that, for all the tragedy and the loss, the U.S. military performed a miracle. After nearly seven years, a constitutional government endures in that country.
It is too often forgotten that all 23 of the writs for war passed by the Congress in 2002 — from enforcing the Gulf I resolutions and stopping the destruction of the Kurds and Marsh Arabs, to preventing the Iraqi state promotion of terrorism, ending suicide bounties on the West Bank, and stopping Iraq from invading or attacking neighbors or trying to acquire WMD — were met and satisfied by the U.S. military.
It is also too often forgotten that, as a result, Libya gave up its WMD program; Dr. Khan’s nuclear franchise was shut down; Syria left Lebanon; and American troops in Saudi Arabia, put there as protection against Saddam, were withdrawn. Perhaps a peep about some of that—especially the idea that in an oil-short world, Saddam Hussein might have been more or less free to do what he pleased again in Iraq. (The verdict is out on Iran; playing a genocidal Hussein regime against it was morally bankrupt. Currently, Shiites participating in consensual government could be as destabilizing to Iran in the long run as Iranian terrorists are to Iraq in the short run.)
Furthermore, the destruction of al-Qaeda in Iraq helped to discredit the entire idea of radical Sunni Islamic terrorists, and the loss of thousands of foreign radical Islamists in Iraq had a positive effect on U.S. security — despite the fallacy that we created them out of thin air by being in Iraq.
Kurdistan was, prior to 2003, faced with the continual threat of genocidal attacks by Saddam Hussein; today it is a booming economy.
All that would have been impossible without U.S. intervention.
With a bit of help from Australia and others.
