I think Guatemala is winnable. The people are peasants, a group whom we tend to have positive feelings toward. The indigenous peoples are Mayan. The non-indigenous peoples are overwhelmingly Catholic, which we understand.
Plus, the whole business with the Guatemalan government using eminent domain on United Fruit land -- at the greatly reduced prices which it was carried on the tax rolls due to previous corruption!! -- has always struck me as snookering them fair and square.
We'd need a little luck. For example, a little bit of bravery on the part of the corporate media to begin the story and get the ball rolling, and then they could end up competing with each other. But I think it could be done.

With Iran, well, it's just a tougher sell from the beginning. First off, Arabs are usually depicted as bad guys in the movies. And I know the people living in Iran are Persian and speak Farsi, but that point might get lost in the wash.
And then, the government of Iran nationalized British oil holders in the manner stated by British law. Which at first glance might seem like a stroke of genius. But on second look, this is exactly the type of thing which would really rile up the British, get them thinking, We'll be damned if we're going to have our inferiors telling us how to do things! Paradoxically, the Iranians should have taken a harder line initially and then negotiated some of the way or maybe two-thirds of the way to this.
