Sorry, pal. Just because you say that the Palestinians didn't do such a thing, when the Israelis caught them red handed doing it, doesn't give the Palestinian Red Crescent lisensce to smuggle arms and terrorists from place to place. The PRC is an arm of Fatah, and they have done this for some time.
The Israelis have a right to defend their civilian population. If stopping ambulances contributes to that mission, then so be it.
Were you more outraged than you appear to be about the systematic murder of Israeli civilians, I might give your argument some credence. Since you aren't, I don't.
Be Seeing You,
Chris
