You both forget. Israel can mobilise its entire population in a matter of minutes. Remember. 6 Arab armies attacked in '48 and lost. They pre-emptively attacked in '67 and the Arabs lost. They were attacked (by surprise, totally unprepared, since it was Yom Kippur) in '73 and the Arabs still lost. If the "Palestinians" attempted to attack, they would probably get their asses handed to them, and if any other Arab nation tried it, they would likely face a repeat of the last three times they attempted it.
