Old Guy, you are misinformed when you say,

"Maybe if Clinton had taken Al Quaeda seriously after the first twin towers bombing there would not have been a second one."

As a matter of fact, Clinton aborted an attack on Los Angeles International Airport. The were a number of others that were deterred under his watch as well. He took Al Quaeda much more seriously than Bush did who claimed that it was not a priority for him in a speech that he gave. "I don't know where he is and (to paraphrase) I don't think it's that important".
