Ah, I see the Clintonian verbal dodge now (sometimes it takes several readings to spot the weasel words). True enough, you didn't say it MUST be a bomb to be terrorism. You simply said it WOULD have been terrorism if a bomb had been used, but a knife or gun, apparently, is not. Which means my initial point stands - is a Palestinian using a gun or knife against Israeli targets NOT terrorism? It's telling you never bothered answering that one.
I guess box cutters don't count either, then.
