How about, "All terrorists are terrorists"
That seems to make sense to me. As a Jew, I know I should probobly have more hatred in my belly than I do but this really happens all over the world.
There are terrorists in every country and in every era. So long as some faction desires more power, this will continue.

I had lunch the other day with a guy from Iran and we agreed that we could never do this in our respective countries (I have birthright) but in America, we can put that aside and have a meal together (we eat pretty much the same stuff anyway).

Terrorists are bad people. Just leave it at that.
