I guess I wasn't very clear. I was talking about the persistence of organized terrorism from organized groups of Palestinians, not lone nuts.

For example, had Timothy McVeigh been part of an organized group of hundreds of terrorists, with new guys going out to blow up government buildings every couple of weeks, and had over fifty percent of Americans surveyed enthusiastically supported him blowing up government buildings, we would have a very different scenario than we do with the small group of nuts that actually did the crime and were universally condemned for it.

Of course, if you are among those who think McVeigh was working for Islamic terrorists, we have another picture altogether, but despite the best efforts of right-wing conspiracists, I have yet to be convinced of that.
