One of my coworkers was once in the Air Force where he worked at a missile silo in combat targeting. For launching missiles, only officers have sufficient authorization to select a target at which to direct a missile, while for the most part only enlisted personnel have the knowledge of how to operate the systems that deliver the missiles to any specified target. Therefore, combat targeting requires pairing enlisted personnel with officers in order to have both the authorization to launch a missile to a specified target and the technical capacity to do so.
Occasionally, the Air Force would send inspectors to rate the capability of the officers to deliver missiles to their targets. Invariably, when the inspectors would come, this coworker of mine was the enlisted airman paired with the officer in order to give the officer the best chance of passing. However, one time that the inspectors came, he was paired with an officer who insisted that he knew all about what he needed to do. Since this officer insisted he knew what he was doing, my coworker simply let him go ahead, and wound up being the only officer to fail when assisted by him.
Donald Trump is essentially that officer. As I have explained before, I can respect decisions reached through a reasonable decision-making process, even ones with which I would disagree or have unease. However, as is clear in Trump's travel order, he thoroughly bypassed the inter-agency process and disregarded everyone in Congress, including those in his party, instead relying exclusively on "security specialists" like Steve Bannon to create his order. The result is an order that disrupts such threats as graduate students conducting medical research and a YU student evacuating the remaining Jews from Yemen while alienating those whose cooperation we need to actually do anything effective about the threat. It is true that there are threats in the world. However, we have procedures in this country to confront these threats and we have professionals, both uniformed and civilian, in government service who deal with assessing whether or not there is some inadequacy in those procedures and, if so, what additional procedures could be implemented that would achieve the greatest improvement in security for the least disruption in societal function.
Like the relationship between that officer to my coworker, Trump is in a position of authority over those professionals. Also like that officer, he lacks the competence to do what he claims is his objective and should rely on those who have the competence. Unfortunately for this country, unlike the officer, there is no inspector overseeing Trump with the power to impose any consequences for his disregard of the expertise of those who know about attacking this nation's challenges.
