Extremely rhetorical question

By now you've heard about the attempted mass murder terror attack that was stopped by Scotland Yard this morning.

Not quite as well known are the other Al-Qaeda terror attacks that have been stopped in the UK and elsewhere in Europe and North America.

Here's the question:

If Hezbollah wins a perceived victory in Lebanon, will this increase or decrease the number of Islamist terror attacks worldwide?

And the followup question:

How come the free world is refusing to act as if they know the answer to this question?
