The group that carried out the attack must be identified and destroyed. That must only be a first step. The frustration of so many people, particularly in the Middle East, is responsible for the rise of despots, terrorists and primitive fundamentalists. There are over two million refuges who have been in limbo for 50 years. Only a few of the lucky ones have been able to emigrate and begin to establish new lives elsewhere in the world, a number of them live in my city and they are good citizens. Fear of domination, subjugation and occupation is rife in the countries of the Middle East and the will follow leaders who can show strength. It has reached a point where strong action is needed. It will take, I believe, occupation by UN forces (or unilateral occupation if necessary) to guarantee boundaries and promote stability. It will be bloody and take a long time but the inaction of the last 50-80 years has created the situation. If nothing is done, there will be more and more of these attacks. Our armed might can win wars, but there is no defence against small fanatic groups unless we become a country with severely restricted liberties.
