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.

U.S. power extends beyond the military and economic spheres to include policing. The United States has used its global policing power to capture terrorists, warlords, and drug kingpins. But extradition is not simply a bureaucratic tool. States’ geopolitical interests shape their willingness to cooperate with others in extraditing fugitives. 

An analysis of Taiwan’s military value concludes that its reunification with China would improve Chinese submarine warfare and ocean surveillance capabilities, tipping the military balance in China’s favor. These findings have important implications for U.S. operational planning, policy, and grand strategy.

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.

Recent quantitative scholarship uses warhead counts to examine whether nuclear superiority offers political or military benefits beyond having a secure second-strike capability. These analyses overlook other elements of a state’s nuclear capability such as state perceptions and beliefs.

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.

States frequently acquire proof that other states have violated norms. Yet, existing theories do not fully explain how states wield such proof to coerce wrongdoers. Four case studies of nuclear proliferation probe a novel theory of how states coerce norm violators by concealing, sharing privately, or publicizing proof of guilt.

Wedge strategy theory explains how states use strategic arms control to divide adversaries by affecting their trust, threat perceptions, and beliefs about a commitment’s trade-offs. Examining three landmark arms control negotiations shows how the wedge motive was a key component to these negotiations.

White Southerners opposed to Reconstruction used violence to undermine Black political power and force uncommitted white Southerners to their side. Although structural factors made it harder for the U.S. government to suppress this violence, a series of policy failures prompted Reconstruction’s failure and generations of injustice.

Trump tied American jobs to endless wars in the Middle East. Biden should link them to renewed diplomacy.
