Europe

Stephen Walt elaborates on the multiple obstacles that Europe faces on the way to military autonomy.

Kari A. Bingen and Heather W. Williams write that if Russia plans to deploy nuclear weapons in space to target satellites, the threat is definitely serious—and the U.S. should act fast.

For Ukraine to maintain its defense and decisively thwart Russia’s invasion, it will take steadfast commitments from Western allies providing both state-of-the-art equipment and basic warfighting needs, local industry leaders and factory workers readying equipment for the frontlines and developing innovative technologies, and civilian volunteers tirelessly filling in the remaining gaps.

From July 11-12, 2023, NATO leaders gathered in Vilnius, Lithuania for one of the most significant NATO summits in history. This timely brief by Eric Rosenbach, Grace Jones, and Olivia Leiwant serves as a background piece on Ukraine’s history with NATO, potential future pathways for accession, and the operational impact Ukraine’s NATO membership could have on the alliance. 

Contrary to the conventional wisdom, military innovation can degrade a state’s military effectiveness as well as strengthen it. In fact, innovation is a gamble that a state may lose, particularly if it is already overextended in its commitments. 

The authors argue that amid the continent's gravest threat to peace and stability since 1945, Europe needs a reliable, serious, focused Germany—not a chancellor and policy elite who need to be pushed and dragged to move.

Modern states recurrently buttress their militaries with legionnaires—soldiers who are neither citizens nor subjects of the governments for which they fight. Legionnaire recruitment is a function of political constraints on a government's ability to enlist citizens and its perceptions of external territorial threats.

At one point in human history, water’s importance in war went beyond bearing convoys, hiding submarines, and slaking soldiers’ thirst. Water was often itself a weapon. In areas where it was scarce, armies took action to make it scarcer to force besieged enemy cities to capitulate, and in areas where it was abundant, combatants destroyed dams and watched the resulting floods carry their adversaries away. Today, however, most combatants recoil at the use of water as a weapon, and only the most depraved deploy it.

If the United States were to withdraw from Europe, any European effort to develop an autonomous defense capacity would be fundamentally hampered by profoundly diverging threat perceptions and severe military capacity shortfalls that would be very costly and time-consuming to close.

Since the end of World War II, nation-states in international conflict have made concerted efforts to restrain the weaponization of water. Distinct from realist and rationalist explanations, the historical record reveals the rise of an international normative inhibition—a “water taboo”—on using water as a weapon.
