The destruction of DOD’s Office Net Assessment is an enormous mistake. This was a little-known but enormously consequential fifty year-old institution that actually thought long-term. It helped us win the Cold War, grasped the China challenge early, and figured out revolutions in warfare. The PRC was obsessed with it for good reason (see below). When I was at the NSC, ONA produced some of the best analysis anywhere in the USG and had enormous and even historic policy impact. No other institution presently can do what it did. Ending it is another unforced error.
