One thing radical Islam has is patience. They can wait until we become lax and drop our guard before attacking us again and attack us again they will. When we become too complacent again they will attack. They are not hiding in caves, they are living normal lives in the countries in the middle east which support terrorism and there are more of those countries than you think, not just Iran, Syria and Lebanon. They will attack us again, the only question is, will they be able to use some sort of nuclear weapon to do it? When it comes I just hope it will be in your city and not mine.
