After 13 years of war, the loss of many thousands of lives, and the expenditure of trillions of dollars, what has the United States learned? The answer depends on not only who is asking but when. The story of the Iraq war would have different endings, and morals, if told in 2003, 2006, 2011, or 2014, and it will continue to evolve. As for Afghanistan, the narrative there has also shifted over time, and the ending also remains in doubt. Neither disaster has been unmitigated. But few would argue that Washington’s approach to either has been a success worth emulating. So the most important question today is what can be learned from the failures.
Two of our authors, Max Boot and Richard Betts, offer starkly different answers. Boot argues that even though Washington is fed up with counterinsurgencies, it will still end up waging more of them down the road, and so should focus on learning how to fight them better. Betts, by contrast, thinks Washington should go in the opposite direction: fighting fewer and more traditional wars and avoiding getting entangled in the domestic politics of chaotic countries on the strategic periphery.
Rick Brennan, for his part, argues that even the best planning is worthless if not ably executed and updated as conditions change. Iraq’s current turmoil, he writes, is the predictable result of the United States’ premature exit, and he worries that a similar fate awaits Afghanistan.
