I think that Zaknafien isn't in support of terrorism, but is simply annoyed at the hypocrisy of the situation?

Seems like brinkmanship on the behalf of Iran really. I doubt they have the true ability to take on Iraq if the US is implicitly involved in one way or another.

But whatever happens Iraq will never be stable nor supportive of the USA, if they wanted that the US should have proceeded with the reconstruction in the same manner as they did in Europe after WWII.

So all in all the Middle East is a mess really.
