Implementation of the NATO Brussels Summit decisions will enhance deterrence and defence on the Alliance’s Eastern Flank, especially through an improvement of the ability to mobilise and deploy larger reinforcements. At the same time, NATO members’ different threat perceptions, including their view of Russia, remain a challenge. Maintaining the U.S. in the lead role will be key to further adaptation but this position could be weakened by growing transatlantic tensions and dissonance in the American administration.
