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? In this monograph, John R. Deni and Lisa A. Aronsson assess whether US allies and partners in Europe can continue providing military assistance to Ukraine or expand assistance, while preserving their own national security and fulfilling their NATO commitments. They also explore what the Russia-Ukraine War reveals about the role of European allies in future iterations of strategic competition. Their findings indicate European allies remain firmly in support of assisting Ukraine politically, even if the reasons for allied support vary across Europe. Despite agreeing support is necessary, European allies face several hurdles on the path toward scaling up military assistance to Ukraine. The reasons for the hurdles vary, and some exceptions exist, but Deni and Aronsson find without continued, sustained US engagement, leadership, and presence in Europe, Washington may find itself with few European allies by its side. To facilitate and sustain continued success in transatlantic burden sharing, the authors provide several practical recommendations for US policymakers to consider.
