Egoz, sorry I kinda jumped on you (Navy Seals did kinda suck). It is true that terrorists bombings rarely (arguably never) get as bad as 9/11, which currently holds the position as THE worst terrorist attack of all time. It took a lot of planning and tons of luck to pull off, and that is why I believe that insurgencies are the future tactics of Al Queda and other terrorists organizations. The insurgency in Iraq has been a very effective tactic for Al Queda so far, though I do not believe they will win I will admit they are a formidable enemy. They may try to stage these takeovers in Europe, East Asia, and possibly even The United States. When they try, you can bet other terrorists and rebel organizations will try as well. They will not work together but they will try their luck at staging an attack. Imagine that in the west, Radical Islamists begin attacks inside US and European cities, at the same time or soon after Neo Nazis kick back up. Communist revolutionaries attempt hostile takeovers, and even possible attacks from those ALF wackos. It could get sticky real fast, especially since militaries will be heavily restricted, fearful, and hesitant do to the fact that they will be fighting in cities filled with their own countrymen. Believe you me, it could get bad.
