Excellent article including this:
"Our mission every day is to provide deterrence," offers [USAF Captain Amber] Moore. "Every day we try to make our enemies ask themselves the question, Does the benefit of attacking the U.S. outweigh the cost? Because they know that we're always prepared to fire back." Readiness is imperative. A missileer's day-to-day is a lot of maintenance, a lot of making sure each ICBM is in tip-top shape, able to sail over the arctic circle instantaneously.The article also notes, "It's all very sensical and comforting until you remember that the order to launch a nuclear missile can only come from the President of the United States, a man who should ostensibly be held to PRP [Personnel Reliability Program] standards...but seemingly is not."
I would say that the American people had ample opportunity to incorporate this concern into their votes and each voter made their own choice on this matter.
Certainly, candidate Clinton and multiple pundits raised the issue of command fitness for the US nuclear arsenal on multiple occasions -- so it's not like voters were never informed of this prior to casting their votes.
