Iraq....
Withdraw major peacekeeping operations to strictly defensive operations around bases...keep bases to a minimum (situated near oil fields preferably). Conduct air raids when necessary but in general let them sort their differences out...because there isn't a force on this planet that will unite them other than them themselves...and to try and help from the outside is just going to get us nowhere. If they want training from our forces, sure...but at the end of the day, it's up to them to patrol their streets...we'll sell them outdated weaponry if requested, but know that the weapons will most likely be used against us in the end we make sure that there's adequate defense against it.
Iran....
Let them develop their nuclear weapon, but warn them that any attempt at using it will result in every settlement being visited by a nuclear device, no matter how small. Ask them if they're willing to trade their entire country for one Israeli city...and let them know that should we even catch a whiff or even suspect for one second that they are giving nukes to terrorist organisations then their entire nuclear program will be dismantled by a team of B-52s, and most of their military force will be likewise dismantled by force.
Israel-Palestine.
Attempt to negociate a definative border zone and then carefully monitor it with all kinda equipment...warn each side that whoever transgresses the zone will lose land by force. If Palestine decides to blow a group of buses up, it'll lose a mile or two of land...and if it continues on a course of violence against its neighbour then it will gradually cease to exist. Likewise for Israel...although land decreases will have to be made according to relative size, since Israel is a bit bigger than Palestine.
I'd probably be destroyed by a terrorist bomb after two months...but that's one way of going about it I guess
