Chinese strategists increasingly believe that U.S. nonnuclear strategic capabilities threaten China’s nuclear forces. Although there is limited evidence of a shift in its nuclear strategy, China is changing its strategic posture to ensure its second-strike capability, including by relying on advanced conventional weapons (e.g., counterspace capabilities, cyber weapons, and electronic warfare) that can target U.S. missile defense. The dynamics of a nuclear-conventional entangled security dilemma may weaken arms race stability.

Many accounts of the formation of American and British grand strategy during World War II between the fall of France and the Pearl Harbor attacks stress the differences between the two sides’ strategic thinking. These accounts argue that while the Americans favored a 'direct' Germany-first approach to defeating the Axis powers, the British preferred the 'indirect' or 'peripheral' method. However, a review of Anglo-American strategic planning in this period shows that before official U.S. wartime entry, both sides largely agreed the British 'peripheral' approach was the wisest grand strategy for winning the war.

When the U.S. military trains other states’ forces, it tries to impart liberal norms such as respect for human rights. But when liberal norms clash, these soldiers prioritize loyalty to their unit, the military, and shared goals.

Rather than revolutionizing war, drones demonstrate its evolution. The principle of air warfare remains avoiding exposure to the enemy. Drones are unlikely to shift the offense-defense balance toward the offense because they are vulnerable to attacks from the ground and air.

The costly Ground-based Midcourse Defense system remains unproven and unreliable in deterring North Korea’s threat to use intercontinental ballistic missiles. An airborne boost-phase intercept system may offer an alternative defense against North Korea without threatening Russian or Chinese deterrents.

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.

When aligned states consider disclosing secret information about military plans to use force, the state initiating these plans may choose among four information-sharing strategies: collusion, compartmentalization, concealment, and lying. Three main considerations shape its decision: potential costs of deception, the partner’s intentions, and the partner’s capabilities.

Carpenter and Montgomery replicate a key question from Sagan and Valentino’s landmark survey of U.S. attitudes toward the laws of war and introduce variations into Sagan and Valentino’s experiment. The findings reveal Americans’ strong belief that targeting civilians is wrong, and that a majority would likely oppose such action in real life.

The administration of President Donald J. Trump has consistently used fear of China to undermine nearly five decades of bipartisan consensus on US–Russian nuclear arms control. The negative consequences of these actions may last far beyond the Trump presidency. If generations of agreement between Democrats and Republicans on bilateral nuclear treaties with Russia erode, it will pose a significant setback to US national security and global stability. Future leaders may ultimately need to consider new approaches to nuclear risk reduction that preserve the benefits of the arms control regime.

When and why do rising states prey upon or support declining powers? A state’s choice of policy toward a declining power depends on two factors: whether that power is useful against challengers to the rising state, and the declining state’s military strength.
