I have a better option—less expensive, infinitely more efficent, and 100% effective:
Kill them all, Hamas, Hizbollah, Al Aksa Martyrs Brigade et al, etc, all the political leadership of all palestinian organizations, level the ground wherever palestinians live, deport all arabs from Israel, deport all survivors to Jordan or whatever hell-hole they can economically march them off to, and outlaw both Islam and Marxism on Israeli territory as existential threats to the nation.
Or continue to waste blood and treasure seeking defensive solutions rather achieving total victory over the enemy.
If the Arabs ever were to defeat Israel militarily (Thank God that will never happen) the Mohammedan Arabs would kill every Jew, old, young, male, female, infants and children.
Anyone who does not understand the aims of the Mohammedans surrounding the nation is suicidal at best. KILL THEM ALL IF YOU CAN AND DEPORT ANY SURVIVORS.
Oh, I forgot, God is going to see to that—never mind...
Be patient my Jewish friends. God will repay them.
G-d is the only one with the right to advocate your solution, too. Unless He is talking directly to you, as he did to Moses and Joshua, let it be. He will take care of it all in the end. Mean time, that three-level shield sounds pretty awesome.
