I read on here the other day from someone who studied Al-Qaida and was a part of the terrorist watch group with the FBI that when they plan something it has to be 100% that the plan will work before they attempt it. He was saying they wouldn't dare risk it even if it was a 75% risk. Which is interesting. Just thought i'd throw that in here.
Al Qaida (and similar groups) want to be seen as always successful. If there's regular news about their plots failing, their backers quit backing them and move on to a group that fails less.
