I wrote the following comment at my favourite right-wing blogger - Carol Platt Liebau.
If you take 9/11 out of the equation, America has been spared pretty much any terror activities by Islamic terrorists.
One theory for this is that America has been able to engage them in Iraq rather than on American soil - but that argument seems to fall down when one considers terror attacks in places like London, Madrid and Bali.
There's no doubt that America's internal security arrangements since 9/11 have helped enormously. However, given the problems of illegal immigration and illegal drugs entering America, it is obvious that many holes still remain.
So why aren't the Islamic terrorists exploiting these security holes?
I would argue that the reason is because the Islamic terrorists were never as sophisticated or well planned as we would like to believe. They do not have the wherewithal to take advantage of America's security holes without being noticed.
Which means, of course, that 9/11 was actually a lucky event, rather than the beginning of a well planned assault on America.
Islamic terrorism has not been, and never will be, a threat to world peace in the same way as Soviet Communism was in the 1950s and 1960s.
