Transatlantic Tensions in the New National Security Strategy

By: Andrea Kendall-Taylor and Jim Townsend

On December 4th, the Trump administration released its long-awaited national security strategy, sending another round of shock waves through the transatlantic community. The National Security Strategy acknowledges that Europe remains strategically vital to the United States and doubles down on the need for Europe to take more responsibility for its defense, but the strategy is unique in its condemnation of allies, focus on “civilizational erasure”, and promise to intervene to “help Europe correct its current trajectory.”

While the 2017 National Security Strategy explicitly laid out several threats Russia poses to American interests, this one makes little mention of Russia except for calls to restore strategic stability. Many of America's European allies are feeling unsettled and concerned about what it means for transatlantic relations. To help us understand the new National Security Strategy, how it differs from Trump's first strategy and where the through lines are, we're excited to welcome Nadia Shadlow and Rebecca Heinrich to Brussels Sprouts.
