Iran is a singular nation... the kingdom of Christ is not on the national level, it just takes over the seat of the Beast, the emperorship if you will, or what do they call the chancellor of the European Union? ...this position controls finance, trade, and war. It doesn't reside within the governments of the nations, it sits on top of the nations... and teaches them to grow up. First the Beast will take them all to war, and oppress them through money, but when Christ sets up his return, he obliterates the political status quo, (not the physical earth) and stands in the same seat of authority... but does a lot better job of leading the nations... for their benefit and for the benefit of their people. In fact, you could say the difference in rulership is night and day. Iran is not a good picture to use to envision the coming kingdom.
