As a US citizen, I wish to assure the good people of Israel that I am equally concerned about your fears of Iran as you are about the price we pay here for gasoline, or the treasure we spend on foreign wars.

You have the military and the money to prosecute your own wars. And if you don't, then perhaps your foreign policy should take that consideration into account.
