There is a qualitative difference between attacking military targets, and attacking civilians. None of the resistance groups fighting the Nazis ever blew up buses in Berlin. Begin may have demolished part of the King David Hotel, but it was the part that the British were using for military purposes. Going after leaders of beligerent, hostile groups is not the same as walking into a disco and blowing it and yourself up. Not being able to get at "legitimate" targets (although an agreement was signed that even this wouldn't be allowed by the PA) does not excuse Palestinians going after buses and discos. Okay, so will you now tell me that all Israelis are legitimate targets, as well as the Jews who send money? I've heard that one. It is even less reasonable than the "dehousing" policy of the RAF during WWII.
