Obama has set us up for failure. No way he is going to attack those Iranian ships. He desperately wants that nuclear deal and will do anything to get it.
And you’re right; in the end our ships will be there only to “maintain the peace”. In the process we will be made to look even weaker and the U.S. will be taken down yet another notch.
As usual, the “Republican controlled congress” will sit there and do nothing. Situation normal.
