Well, last week you were terrified of N. Korea, now it seems you are terrified of Iran, might I suggest backing away from the computer for a while.  The odds of either of those nations nuking us are extremely low.  If, however we keep threatening them, those odds get greater.  In both cases, they for the most part want us to leave them the hell alone.  The Iran deal, while not optimal, is better than nothing.  Nothing is what we have with N. Korea and look where we are now with them.
