Diplomacy is about the little things

Iran tries to extend negotiations, throwing out the US plan, and adds this little snub.

He gave the reply to ambassadors from Britain, China, Russia, France, Germany and Switzerland, state-run television said, without disclosing details.

By the way, has anybody else noticed that the last 50 years of middle east conflict are being repeated in order, in reverse?

Iraq invasion (1991.)
Iraq/Iran war (84-88-Iranian backed civil war in Iraq)
Israeli Invasion of Lebanon (1982)
Diplomatic tension with Iran (1980-nuke program now.)

If four points make a line, the next event would be the Israel/Egypt peace accord followed by a repeat of the '67 Arab-Israeli war. (I don't really believe this, but it is an oddity.)

The one difference I would note is that none of these current repeats are turning out as well for the US as their predecessors.
