The USA was willing to go to war with Russia if Russia didn't pull its missiles from Cuba. Russia did the smart thing and took away the rockets. Hezbollah doesn't think rationally. They are motivated by jihad and regaining Israel for Dar al-Islam, the Land of Islam. For Israel to think that anyone, the UN or Santa Claus, can make Hezbollah destroy all those rockets, is dangerous delusional day-dreaming.
Israel and Israel alone is responsible for its security. If they have proof of tens of thousands of rockets, then it is up to Israel to find them and destroy them before they are used against her.
Even the USA, with Obama at the helm, will make preemptive strikes against Islamist psychopaths. Israel should do no less. I understand that Israel has to take the first 'hit' so that the world won't condemn it for protecting itself, but after that first attack by Hezbollah, Israel's response has to be cataclysmic and permanent: Hezbollah will be destroyed to the last rocket and to the last man. No more warnings, no 'knock-knock' bombs, just pure evisceration of a warped culture. Nasrallah can gloat from his cave, but any attack from Lebanon will result in southern Lebanon being turned into new Israeli land and Hezbollah will be just a bad memory.
