@MontereyJack,
Nice try, but threats only work in changing someone's behavior if they can avoid the threat by changing their behavior.
You've already pledged that Israel will be attacked no matter what they do.
Since the rockets will be launched no matter what Israel does, they may as well keep all the land.
Better for Israel to "keep the land and have the rockets launched at them" than to "give up the land and then have the same rockets launched at them anyway".
