You comparison is a nonsense. Austin do not have Mexico totally surrounded by land sea & air. Austin does not stop the necessities of life from entering Mexico so that people are living in hell. As to "warning" a people who have no way of escape that they are going to be bombed and bulldozed to Kingdom come, that was just a cynical exercise thought up by one of the increasingly warped minds in charge in Israel and no one but the very gullible, gives it the time of day. Take your head out of the sand and see what the rest of the world is seeing, then your responses might just be a tad plausible.
