Former Defense Secretary Robert Gates writing in the Wall Street Journal:

Mrs. Clinton has time before the election to address forthrightly her trustworthiness, to reassure people about her judgment, to demonstrate her willingness to stake out one or more positions on national security at odds with her party’s conventional wisdom, and to speak beyond generalities about how she would deal with China, Russia, North Korea, Iran, the Middle East—and international trade. Whether and how she addresses these issues will, I believe, affect how many people vote—including me.

At least on national security, I believe Mr. Trump is beyond repair. He is stubbornly uninformed about the world and how to lead our country and government, and temperamentally unsuited to lead our men and women in uniform. He is unqualified and unfit to be commander-in-chief.

Former Defense Secretary Robert Gates derided the Republican party’s candidates for an understanding of national security issues that “would embarrass a middle schooler,” the Guardian reports.

Said Gates: “People are out there making threats and promises that are totally unrealistic, totally unattainable. Either they really believe what they’re saying or they’re cynical and opportunistic and, in a way, you hope it’s the latter, because God forbid they actually believe some of the things that they’re saying.”

“Carpet bombing would be completely useless. It’s totally contrary to the American way of war. Total disregard for civilians. So, I mean, part of the concern that I have with the campaign, particularly when it comes to national security, is that the solutions being offered are so simplistic and so at odds with the reality of the rest of the world, with the way the world really works.”
