He's too busy reading the Neocon manual for talking points in keeping the U.S.A. in the middle east, indefinitely, in ongoing wars one right after the other until nuclear weapons are involved, and then the REAL fun begins.
Iran is backed by two nuclear powers, China & Russia.
Don't think for a minute that if we get into a military confrontation with Iran, that is more than just a minor skirmish that they will not magically come into the possession of nuclear armaments with the express purpose to use them against our military strike force.
Multiple Nuclear tipped missiles coming inbound from different directions, one is bound to get through, and it only take one to sink an entire carrier with ancillary damage to it's strike force.
It would be a nightmare, and it's in the foreseeable future if Romney gets elected.
This guy makes the grim reaper look like the tooth fairy.
