"Franklin D. Roosevelt relied heavily on a kitchen cabinet. Harry S. Truman created the National Security Council to formally weigh options and coordinate among departments fighting the Cold War. Richard Nixon and Jimmy Carter turned the N.S.C. into an idea generator. In the Obama administration, members of the N.S.C. staff talked about 'death by Situation Room meeting' and compared the process of policymaking to watching a python swallow a pig."
From
"Trump Follows His Gut. His National Security Advisers Try to Keep Up. Decisions come fast, even if contradictions and inconsistencies abound. But without much of a process, there is little preparation for how things can go wrong" (NYT).
And Trump? He has, we're told, "reduced the size of the N.S.C. staff by at least two thirds.... And when debates take place, the number of players often shrinks to a tiny group.... Not much leaks from those sessions, a major change from, say, the early Obama era, when Situation Room conversations sometimes appeared on news websites before the meetings were over."
So then we don't really have a way of knowing what goes on. Well, the NYT writer, David Sanger, presents us with a quote from Thomas Wright, "a scholar at the Brookings Institution who worked on long-term strategic planning in the National Security Council during the Biden years," who purports to tell us what "Trump seems to think," which is that "he doesn’t need options or contingency plans. He just wants a small team to execute his instincts."
