The War against Terrorism

For some, the main tactics against against terrorism are investigation and intelligence work. But post-9/11 that is supposed to be wrong-headed. We need a pro-active, pre-emptive approach, i.e., invade other countries. So we invaded Iraq. Of course, we do not know what terror plots never got off the ground because of the invasion of Iraq. But one can ask the following questions:

The invasion of which country or countries would have possibly thwarted

1. The attacks of Sept 11, 2001?
2. The Bali bombings of October 12, 2002?
3. The Mumbai bombings of August 25, 2003?
4. The Istanbul bombings of November 15 and 20, 2003?
5. The Madrid bombings of March 11, 2004?
6. The Al Khobar massacres of May 29, 2004?
7. The London bombings of July 7, 2005?
8. The Mumbai bombings of July 11, 2006?
9. The plot to blow up planes with liquid explosives just uncovered by the British?
