Episode notes
Mid‑Century Multilateral Vision Wins Out
- Post‑WWII multilateral institutions like the Marshall Plan and UN created an order that benefited U.S. interests and global stability.
- Christopher Nichols shows historians ranked these mid‑century multilateral steps as the most consequential positive decisions.
Unilateralism Often Equals Failure
- Unilateral, interventionist moves often appear among the worst decisions, from Vietnam to the 2003 Iraq invasion.
- Mary L. Dudziak and Christopher Nichols contrast these with multilateral successes to show a clear pattern.
