The Iranian military revenge was less intensive then I had expected. But it was also a clear sign that Iran is capable and willing to openly attack U.S. bases in the larger area. The missile attack came despite Donald Trump’s threats to Iran. It called his bluff.
Further reactions will depend on the U.S. reactions to the demand of the Iraqi parliament that all foreign forces leave Iraq. Should the U.S. leave Iraq peacefully all will be well. Should it insist on staying U.S. soldiers will die.
