The United States, Britain and the other countries that have sacrificed so much since 9/11 may, understandably, be reluctant to put boots on the ground either to counter insurgencies or to support groups seeking to topple oppressive regimes. In spite of that, however, we do need to preserve the understanding and skills gained from the past decade. Numerous countries and regions face or will face insurgencies. And undoubtedly, it will be in our interest to help at least some of those countries, even if we do so in ways that do not include large military footprints.
