The recent release of the Trump administration’s National Security Strategy marks a significant moment in U.S. foreign and defense policy, outlining how the administration views the global threat environment and America’s role within it. The strategy addresses great-power competition, alliances, economic security, and the use of American power at a time of heightened geopolitical tension – from ongoing conflicts in Europe and the Middle East to strategic rivalry with China. On December 18, the ACG and 1014 hosted a virtual discussion with leading foreign policy and national security experts Nico Lange and Robin Quinville, who unpacked the key priorities and assumptions of the new strategy – and the implications for the transatlantic partnership.
