You need to measure that in months joesbucks not years, when you consider attacks on US interests abroad during that time period. Thankfully we don't have to say the same since 9-11. And had the millenium bomber not been stopped by an alert border agent, we'd have seen something actually on American soil 18 months before we did. The Cole, the embassy etc...these are attacks we know about, other attack attempts that failed may also have occured. One can add in OKC and TWA 800 if you tend to believe eyewitness reports rather than official government positions, but I digress.
I continue to suspect Hussein was indeed sedated. Or in some way rendered unable to protest or resist during the clip of his noosing that's been circulated. I have no proof, of course, but neither do you. But then I also suspect Martha Stewart was on heavy Xanax when her verdict was read too. It's a common practice when tv cameras are sure to be focused.
If you use the comparrison of global attacks, then you would have to consider the daily attacks upon our people serving in Iraq.
The terrorists seem to have the ability to lay low and attack at the most opportune time. They are patient. Think of the efforts we have taken and implemented since 9/11 that certainly would have slowed the domestic opportunity for terrorism. Even so, the administration has admitted that we are still highly at risk domestically. If the Islamofacists were busy on the Iraqi front, then our risk would be much diminished, not still high. It has nothing to do with the terrorists pre-occupation in Iraq. It has to do with timing on their part.
