Here's another strange coincidence. Before Sept. 12, 2001, al-Qaida had major successes attacking U.S. targets. And during that time, al-Qaida had sanctuary from Sudan, then Afghanistan, and possibly Iraq (from sometime in 2002 till March 19th, 2003, al-Qaida definitely had sanctuary in Iraq). And before Sept. 12, 2003, al-Qaida showed great smarts, hitting U.S. targets of high visibility.
What a coincidence that that once we removed their sanctuaries in Iraq and Afghanistan, their power declined.
