Honestly, is their really peace ANYWHERE?
Let alone Iraq.
Iraq is geographically placed that peace will be very hard/close to near impossible.
Mabye a better question would be "Do you think Iraq will ever have a sound political system?"
-B00M!
Basically what he said. That's like asking if hatred will ever end.
If you're talking about if they'll ever form a union or whatnot, then still no. With all the history that's happened in the Middle East there's no way. Probably the only scenario that could make them become united is if their memories were all wiped clean.
For the politically sound question, then still no. It might last for a couple years (or maybe even decades if we're lucky) after the US pulls out, but then some left-winged radicalist is going to come in and take over with an AK and a couple of pounds of C4. Too much going on with religious beliefs for people to just accept how things are :
