This belongs in the beyond ultimate dismal scenario.
Today, it is still not clear whether the U.S. would have shot down the 911 sandmaggot-hijacked planes, if the opportunity had presented itself to do so with minimal damage to anything on the ground. Had we done so, we would be having violent arguments to this day as to the moral justification for doing so.
The Israelis have no such luxury. Not knowing what the two-legged animals may have aboard a hijacked airliner in the way of WMDs makes it a given that they must shoot down any airliner which refuses to communicate with the ground, or refuses to be directed to a remote landing location. Doesn't matter if the captive passengers are all Israelis...
Bigfoot, the Loch Ness Monster, Unicorns, the Minotaur and "moderate" muslims... all mythical beasts.
Great Points (imho)
