The problem is one of mindset. The left mindset. They see terrorism as a crime instead of an act of war. Until that changes, they will keep doing what they have always done.
They don't understand the evil nature of some people. They were taught as children that when somebody kills, someone else must have done something to them to make them that way. This belief was then re-enforced by academics in college. Look at the period Clinton, Kerry et al went to school....and now, Obama
They truly believe that terrorism is a crime and trial and punishment is the way. They still don't understand that 9-11 was an act of war. They are still trying to figure out what we did to "cause" it. They still believe that if everyone has relatively the same amount of money in their pcoket and crap in their houses, most of this will go away.
They are blind to the will to power - which is funny, since they have it in spades themselves.
