Why we're fighting in Iraq

Mark Alexander writes a long and interest article with this as the central point:

Let's be clear: American forces are NOT, first and foremost, 'fighting for Iraq's freedom.' They are fighting for U.S. national-security interests and those of the free world, which was, and to a lesser degree (thanks to our considerable military achievements), remains, in great peril. Ultimately, these two objectives are inextricably bound. Our ultimate objective in Iraq is to establish a forward deployed presence in the Middle East -- military personnel, but primarily equipment -- now that the Saudis have pulled our lease. Our analysts estimate that once the new Iraqi government is seated, the U.S. will be invited to establish permanent military installations in southern Iraq. This presence is critical, given that it would place us in the heart of Jihadistan, with the ability to protect our national interests in the region quickly without having to respond via sea and airlift. Our sources indicate that this new forward presence will be offset by part of our Cold War tactical and strategic assets in Germany.

If you wonder why we ended up in Iraq, and why we're staying there, this is a great column to read.
