Middle Eastern Union?
Come on. You think there will be a "Middle Eastern Union" when the Arabs call most Iranians apostates and use our ethnicity as an insult? And don't make a "Hitler was defeated" comparison, they have been doing this for millennia. Israel will be recognized by Iran when they turn us into their puppets (
never going to happen,
ever) or they cease to be a country in the current form (occupying Palestine, seeking Middle Eastern hegemony etc.).
You want me to look at Europe? Sure, I'll look. I'll look to see the Greeks comparing Merkel to Hitler, to see Britain trying to leave, to see Scotland trying for independence. The whole idea of a "global union" is preposterous and ridiculous.
As for Iran, the reason we lost the land to the Russians was not because we happily handed them over, the stupid lazy idiotic Qajar dynasty fought them and lost, then gave the place up because they were incompetent bastards. Iran isn't as weak as it was in the 19th century anymore.
