NATO's Biggest Threats

In the wake of a very short communiqué and an abbreviated Summit, many questions have been left unanswered by allies. How NATO would manage a reduction of military assets in Europe, support for Ukraine, nuclear strategy, and the rollout of the 5% spending benchmark are all uncertain at the moment, as is the transatlantic relationship.

Constanze Stelzemüller is the Director of the Center on the United States and Europe at the Brookings Institution

Gabrielius Landsbergis is the former Foreign Minister of Lithuania
