What more can US allies in Europe do to assist Ukraine militarily? More broadly, what can the United States expect from its closest allies in Europe in strategic competition with Russia and China? Despite agreeing support is necessary, European allies face several hurdles on the path toward scaling up military assistance to Ukraine. To facilitate and sustain continued success in transatlantic burden sharing, the authors provide several practical recommendations for US policymakers to consider.
America’s relationship with Europe is undergoing a potentially profound reexamination. Whether and how the transatlantic bond — especially America’s commitment to NATO — will endure has become an open question.
Despite notable solidarity and unity in the immediate aftermath of the Russian invasion and significant progress in rebuilding the Alliance’s defence and deterrence architecture, the list of challenges facing the NATO Alliance is significant. This paper focuses on four of the most critical gaps: in the fields of command structure, military capabilities, force posture, and asymmetric defence. It also offers actionable recommendations for progress in advance of NATO’s Hague Summit in June 2025.
