Strategic Myopia: The Proposed First Use of Tactical Nuclear Weapons to Defend Taiwan

| Mar. 14, 2024

David Kearn argues that the idea that the first use of nuclear weapons since 1945 would be by the United States in the defense of Taiwan against a conventional Chinese invasion would have significant, negative, and long-lasting, diplomatic ramifications. It is difficult to fathom the myriad potential consequences, but U.S. nuclear weapon use would almost certainly shatter the non-proliferation regime as a functioning entity, incentivize states (including China) to acquire or improve their existing nuclear arsenal, and damage America's standing globally.

To Enhance National Security, the Biden Administration Will Have to Trim an Exorbitant Defense Wish List

| Mar. 13, 2024

David Kearn argues that even in the absence of restrictive resource and budgetary constraints, a focus on identifying and achieving concrete objectives that will position the United States and its allies to effectively deter aggression in critical regional flashpoints should be the priority given the stressed nature of the defense industrial base and the nuclear enterprise.

Gender Analysis and the Treaty on the Prohibition of Nuclear Weapons: A Response to Daarstad, Park, and Balogh

| Dec. 01, 2023

Herzog, Baron, and Gibbons (HBG) thank Haley Daarstad, RyuGyung Park, and Timea Balogh for replicating their 2022 short article in The Journal of Politics. In that article, HBG tested the malleability of U.S. public support for nuclear disarmament, specifically in the context of the 2017 Treaty on the Prohibition of Nuclear Weapons (TPNW). Their survey experiment reveals that––despite majority public support for eliminating nuclear weapons––Americans’ backing of the TPNW can be significantly attenuated by exposure to elite and group cues opposing the treaty. The resultant article has received considerable attention from policymakers and anti-nuclear activists alike. Daarstad, Park, and Balogh (DPB) offer three main substantive points of comment on HGB's article. First, DPB indicate that the results successfully replicate and note that they “do not find any coding errors that undermine the authors’ analysis or conclusions.” Second, DPB show that the findings also replicate when partisan leaners are coded as political Independents. Finally, and most interestingly, DPB conduct gender-based subgroup analysis and show that there are heterogenous treatment effects among male and female respondents in our sample. HBG address each of these points in turn.

Navigating China’s Opportunistic Approach to Overseas Naval Base Acquisition

| November 2023

This report, by Maxwell Simon (MPP '23) and Jayaram Ravi (MPP '23), explores the drivers of setback and success that China has encountered in the process of developing dual-use and military-dedicated naval installations abroad. It looks at cases where China has considered or actively pursued military-dedicated installations to characterize Beijing’s general approach to overseas naval base acquisition.

Ukraine’s Defense: A Whole-of-Society Effort Demanding Additional Support

| Oct. 13, 2023

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.

Bargaining with the Military: How Presidents Manage the Political Costs of Civilian Control

    Author:
  • Andrew Payne
| Summer 2023

Dominant normative theories of civil-military relations focus on ideal-type scenarios that do not reflect the messy, inherently political character of elite decision-making. A case study of civil-military dynamics during the Iraq War identifies four decision-making strategies that George W. Bush and Barack Obama used to avoid incurring a domestic political penalty for rejecting the military’s preferences.
