The US Army Is Trying to Bury the Lessons of the Iraq War

As has been explained to me by senior officers who are still on active duty, the conventional wisdom today is that our military has moved on — and in an odd redux, they note that we have returned to the philosophy of 1973. Similar to how the Pentagon abandoned its doctrine of fighting counterinsurgencies and irregular conflicts in the aftermath of the Vietnam War, today’s military has shifted away from the wars in Iraq and Afghanistan. Instead of preparing to fight insurgents and guerrillas, our security establishment has refocused almost exclusively on the realm of great power conflict — in their parlance, peer or near-peer competitors such as Russia or China.

This trend away from “small wars” has been so intense that it contributed to Army’s resistance to publishing its own Iraq War Study, a project that I helped lead to its conclusion in 2016.
Even major wars require that we incorporate the lessons from small wars. Winning major battles in small or big wars is never sufficient to achieve our political aims. It is beyond shameful if we repeat the same mistakes again.
