You're Iranian, you should know your country better than the others. But if you ask me, an ignorant Indonesian fanboy, I'll say that Iran is not alone. Or at least, Iran think that they're not alone. But who know.
I think Iran doesn't has any choice. This is a do or die situation for your country. At a time like this, your resolve as a nation will be judged. Are you going to be your own country enemy, or you will be united under 1 banner and fight the aggressor. If there is a traitor among you, and he got a majority support from another Iranians, then it's a game over for Iran. Because that kind of tactic is basically American and Israeli's favorite one. But if Iranians can be united, the aggressor won't be able to break you.
