in our life now? >> you are right. i remember, i remember as say student, going to paris, they had sealed all of the crash cans, a number of algerians in france were engaged in a civil war, where, they put bombs in the trash cans and conducted a series of terrorist attacks. if you remember, communist groups from shining path to red brigade bombing discos, airports. the munich olympics, terrorism is a tactic, it has been a tactic of brutes for decades, if not centuries, there there a difference with a religious and ethnic overlay. i just want to stress, that attacking innocent people because of their background, that is not the answer. and you know, that is escalation, if that is what it is, that is really frightening.
