I. HE DISDAINS EXPERTISE
Trump has little interest in the details of policy. He makes up his mind about a thing, and those who disagree with him—even those with manifestly more knowledge and experience—are stupid, or slow, or crazy.
II. HE TRUSTS ONLY HIS OWN INSTINCTS
Trump believes that his gut feelings about things are excellent, if not genius. Those around him encourage that belief, or they are fired. Winning the White House against all odds may have made it unshakable.
III. HE RESISTS COHERENT STRATEGY
If there is any broad logic to Trump’s behavior, it’s Keep ’em confused. He believes that unpredictability itself is a virtue.
IV. “HE IS REFLEXIVELY CONTRARY”
General H. R. McMaster, who left the White House on reasonably good terms in April 2018 after only 14 months as national security adviser, is about as can-do a professional as you will find. He appeared to take Trump seriously, and tailored his briefings to accommodate the president’s famous impatience, in order to equip him for the weighty decisions the office demands. But Trump resents advice and instruction. He likes to be agreed with. Efforts to broaden his understanding irritate him. McMaster’s tenure was bound to be short. Weeks before accepting his resignation, the president let it be known that he found McMaster’s briefings tedious and the man himself “gruff and condescending.”
V. HE HAS A SIMPLISTIC AND ANTIQUATED NOTION OF SOLDIERING
Though he disdains expert advice, Trump reveres—perhaps fetishizes—the military. He began his presidency by stacking his administration with generals: Mattis, McMaster, Kelly, and, briefly, Michael Flynn, his first national security adviser. Appointing them so soon after their retirement from the military was a mistake, according to Don Bolduc, a retired brigadier general who is currently running as a Republican for the U.S. Senate in New Hampshire. Early on, the biggest difference Bolduc saw between the Trump administration and its predecessors, and one he felt was “going to be disruptive in the long term,” was “the significant reliance, in the Pentagon at least, on senior military leadership overriding and making less relevant our civilian oversight. That was going to be a huge problem. The secretary of defense pretty much surrounded himself with his former Marine comrades, and there was, at least from that group, a distrust of civilians that really negatively affected the Pentagon in terms of policy and strategy in Afghanistan, Syria, and Iraq, by following the same old failed operational approaches.” Trump’s reliance on military solutions is problematic because “there are limits to what the military can solve. I think initially the Trump administration held this idea that general officers somehow have all the answers to everything. I think the president discovered in short order that that’s really not the case.”
