Easier to Get into War Than to Get Out: The Case of Afghanistan

| August 2021

The U.S. should accept with humility its inability to fully eliminate terrorism. Specifically, U.S. policy must balance “ends, ways, and means;” establish clear and achievable objectives; adopt efficient, effective, and resource-sustainable strategies; ensure synchronization of diplomatic and military efforts; build alliances to share the burden of countering terrorism; and leverage cooperative mechanisms and regional partnerships to increase the capacity and willingness of regional states to defend their sovereignty and contribute to multinational coalitions against terrorism.  A balanced, integrated, and synchronized strategy encompassing defense, diplomacy, economic, and humanitarian assistance lines of effort should be cornerstone of a revamped foreign policy in the coming decades.

Leaning on Legionnaires: Why Modern States Recruit Foreign Soldiers

    Author:
  • Elizabeth M.F. Grasmeder
| Summer 2021

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.

The Stuff of Life and Death: Part II

May 04, 2021

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.

Illusions of Autonomy: Why Europe Cannot Provide for Its Security If the United States Pulls Back

| Spring 2021

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.

Water and Warfare: The Evolution and Operation of the Water Taboo

    Author:
  • Charlotte Grech-Madin
| Spring 2021

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.

What Could Cause a US-China War?

| Mar. 02, 2021

Thucydides attributed the war that ripped apart the ancient Greek world to two causes: the rise of Athenian power—and the fear that this created in the established power, Sparta. Joseph Nye advises that in order to prevent a new cold or hot war, the United States and China must avoid exaggerated fears and misperceptions about changing power relations.

The Real Threat to Civilian Control of the Military: The Officer Corps Can No Longer Simply Ignore Politics

| Jan. 18, 2021

The dominant culture of professionalism in the military today maintains a strict separation between the military and civilian spheres and bars officers from thinking about politics. It consequently undercuts the military’s role in ensuring the United States wins its wars and absolves military leaders of responsibility when the country fails to do so. That culture also leads the military to resent when civilian leaders intervene in battlefield decisions, hindering civilians’ ability to scrutinize military activity and ensure it serves civilians’ goals. Simply put, the prevailing culture of military professionalism undermines U.S. national security.
