"What should the U.S. do? The history of civil wars since 1945 provides clear lessons that current policy is ignoring.
Contrary to common wisdom, it is possible for an external power to extinguish someone else’s civil war. Since 1945, over 20% of the approximately 150 civil wars have ended in negotiated settlements. That number increased to nearly 40% after 1991, as in the Balkans, Mozambique, Cambodia and El Salvador, in part because the international community learned how to facilitate such settlements.
