Why the hesitancy in attacking Iran?

You're a Moron but if you want WW3 then go ahead and sacrifice the Life's of Servicemen in the Middle East just to show what kind of a Prostitute the USA is to Israel. Some like to call it the Struggle for the Peace in the Middle East and others are just plain stupid. Answer this question please....How would you finance yet another War? Higher Taxes and Lower wages? Wow you gotta be a smart guy.
