Maybe .. Maybe not .. but I would like to know why Israel thinks it is a terrorist attack
My guess is because they've been conditioned for thirty years to assume any attack on Israeli interests is terrorism until proven otherwise.
If this guy was a terrorist (and I'm not at all convinced that he was; workplace shootings by disgruntled employees are hundreds of times more common than terrorist attacks in the US - I blame Artie), he sure wasn't a very good one, and he definitely didn't seem to have any desire to take out anything that represented America. You'd at least want to head to a US airline's counter for that ... where there are no armed plainclothes security.
