Being attack is not good. But the reaction can often bring peace and unity. I was in Munich during the attack. I did not much o0f it because I could not speak German and my host could not speak English. However on heard it on an English radio news that night. The reaction of the people at the Closing Ceremony united us all as we commemorated those who died. We were united in making sure the Games continued. There has been no attack since except the one on at outside venue in Atlanta,
I am not sure what intellegence the British have but I am not sure an armed response will bring peace. Shooting down planes in civilian areas is dangerous. I think we should be prepared bot not over react.
