The enemy's exit strategy

CNN reports that al Qaeda's second in command Ayman al-Zawahiri has "called on U.S. President George W. Bush to admit defeat in Iraq," echoing the thoghts of John Murtha. He also laid out al Qaeda's terms for peace. One is the usual claptrap about the infidel leaving Islamic territory, but the other one gets to the true aims of our enemy:

"Second, install sharia (Islamic law) on the entire Earth and spread Islamic justice there [...]. The attacks will not cease until after the victory of Islam and the setting up of sharia."

That is what we face in this conflict. Nah, no threat there!
