In November 1979, a group of Iranian militants stormed the U.S. embassy in Tehran, and they took 52 American citizens hostage.  For the next 444 days, the United States was absolutely humiliated by the Iranians.  President Jimmy Carter looked like a pathetic weakling in the eyes of the rest of the world, and his inability to get the hostages back helped to pave the way for the election of Ronald Reagan in 1980.

Perhaps the Iranians were attempting to recapture that magic by having their proxies storm the U.S. embassy in Baghdad, but it is not 1979 anymore, and Donald Trump is not Jimmy Carter.

The Iranians appear to think that they can intimidate Trump the same way that they have intimidated other U.S. presidents, and they also seem to believe that if they put enough pressure on him that the U.S. will eventually relent and leave the region.

But anyone that knows Trump understands that he never backs down.

Throughout his life, he has had a personal rule that when someone hits him, he hits back even harder.
