... that Donald Trump must not win this election, you should read this LA Times op-ed by a Minuteman III nuclear launch officer (who also happens to be a Republican):
[C]onsider Trump’s words in a town hall event during the primaries: “Somebody hits us within ISIS, you wouldn’t fight back with a nuke?” Or the words of Trump’s spokeswoman, Katrina Pierson, who also asked the unaskable on Fox News: “What good does it do to have a nuclear triad if you’re afraid to use it?”
Having spent five years of my life as a Minuteman III launch officer, and a year as an instructor teaching young officers how to run that weapon system, I’m equipped to answer the Trump campaign’s question. The very point of nuclear weapons is that they are never used. We have them to dissuade hostile powers from attacking us, and vice versa.
Deterrence, as this policy is known, has been the backbone of U.S. national security for decades. That a candidate for the highest office in the land needs this explained to him, not once but thrice, should give every voter pause.
During my years in the Air Force, I worked over 300 nuclear “alerts”—24-hour shifts 100 feet below the Wyoming tundra. I sat at my post believing, through both the Bush and Obama administrations, that the president was fundamentally rational and would never ask me to do my terrible duty. Not unless the country was in the direst of national emergencies.
With Trump as president, the young men and women who are assigned to our nuclear forces will have no such assurances.
