I disagree eric.  In an effort to prove she had the "balls," Hillary may well have militarily engaged the Russians which I believe would have led to limited nuclear exchange.  When it comes to MAD, it does not work except in massive exchanges.  The US would be insane to launch a full out assault in response to the vaporization of a few cities.  Recall, that in response to a full assault on the Russians, they will launch a massive strike with every city in the US with population over 100,000 population targeted.  No, Hillary would likely have led to a horrible war.  Trump does not need to prove that he has "balls."
