Not true. Now that we have databases and sophisticated tamper-resistant passports, it's getting harder to buy a functional fake in a back alley. You can get one that will work at a hotel or a border check-point on a east-european two-lane highway, but not one that will hold up at a US CBP screening.

You pretty much need a real passport now, and there are three ways to get one...

- Use your real one.
- Convince/Bribe a sympathetic foriegn government or employee thereof to issue you a real one under a phony name.
- Steal/borrow one from someone who looks a lot like you.

Anti-terrorism is the art of putting roadblocks and random, variable measures to make the bad guy's planning process difficult. High-end terrorists do not conduct desperation operations which have a high risk of failure...this will make them look like idiots in world opinion and, more importantly, to their financiers back home.

Remember, you don't necessarily have to stop the suicide bomber...for every one of those there are five or so support players (logistics, finance, transport, recon, command) who also need to move about freely to prepare the operation. These folks are usually older, more educated, have families...ie a lot more to lose and not so willing to die for the cause. They are less likely to take chances.
