Today’s challenges, from terrorism and nuclear proliferation to cyberattacks and pandemic disease, don’t respect national borders.
Resolutions to these problems are not possible without some degree of American leadership and international cooperation. Maintaining a leadership role in the word does not require, and should not involve, political or military intervention in the affairs of other nations. It does require that we remain committed to international cooperation, and work to shape a new consensus about our role in the world. We cannot veer from intervention to isolation in order to please domestic constituencies or win elections.
