In a twisted sort of way, it was probably better that BJ was too busy with his sink to bother with bin Laden. If 9/11 hadn't happened, all it would have done, IMHO, is put off the inevitable a few more years ... maybe one year, maybe five, maybe 20, I can't say. But I do know that the lunatic fringe of the Arab world has been wanting to destroy the United States for decades, and some group would have managed to pull off something eventually, even if bin Laden had been taken out. And if there had been no 9/11, that something would have happened later, but it also probably would have ended up killing far more Americans than died in the 2001 attacks.
Bin Laden thought he was just getting started. But in reality, he got cocky and overplayed his hand, and America woke up as a result. If the American people and government had been left to sleep until bin Laden or some other wacko Wahhabist group got their hands on serious WMDs, the carnage here would have been unimaginable. As would the size of the US response.
The only point I take exception with. Actually a significant portion of Islam/the Arab world wishes the same for us as Israel. Muslim infiltration in Germany and France as well as the writing of real intellectuals has lead me to this conclusion.
