Flypaper, or just shit?

A month ago David Warren, the author of the "terrorist flypaper" hypothesis for why we should fight in Iraq, wrote the following:

As the author of the much-mocked "flypaper theory" -- the phrase I used to describe the implicit strategy behind the U.S. invasions of Iraq and Afghanistan -- I am more and more persuaded it has worked. All ground indications are that large numbers of Islamist terrorists who would otherwise remain dangerously under cover, not only across the region but in Europe and elsewhere, are irresistibly drawn towards these theatres of action, where they sooner or later get themselves killed.

I wonder how he feels looking at the TV from London today.
