Narratives and War: Explaining the Length and End of U.S. Military Operations in Afghanistan

    Author:
  • C. William Walldorf Jr.
| Summer 2022

A new theory of war duration suggests that strategic narratives explain why the U.S. war in Afghanistan endured and ended. A robust anti-terrorism narrative generated audience costs for presidential inaction. As the narrative weakened, these costs declined, and the war ended.

Book Review: The Taliban at War: 2001–2018

| Sep. 03, 2020

Nathaniel L. Moir reviews Antonio Giustozzi's The Taliban at War: 2001–2018 (New York: Oxford University Press, 2019).  He writes, "Through an assessment of the intra-politics of the Taliban's different shuras, along with the success and failures these shuras have achieved over the recent past, Giustozzi brings readers up to date on the Taliban's organizational status as it moved toward negotiations with the Afghan government."

Paradoxes of Professionalism: Rethinking Civil-Military Relations in the United States

| Spring 2020

The U.S. military’s prevailing norms of military professionalism are poorly suited to meet today’s civil-military challenges. They undermine the military’s nonpartisan and apolitical ethos, weaken civilian leaders' control of military activity, and undercut the country’s strategic effectiveness in armed conflict.

Deploying coal-bioenergy gasification systems with carbon capture and storage (CBECCS) provides a promising opportunity for China to realize its carbon mitigation and air pollution abatement goals simultaneously. The authors conducted a comprehensive assessment of CBECCS technology for China, with a focus on plant and fuel configurations (e.g., biomass ratios) and economics, as well as CO2 and greenhouse gas emissions and cobenefits for air quality.

Buying Allies: Payment Practices in Multilateral Military Coalition-Building

    Author:
  • Marina E. Henke
| Spring 2019

Many states have been paid to join multilateral military coalitions. These payments are largely covered by “pivotal states”—those that care the most about an operation’s success—and take the form of deployment subsidies and political side deals to attract critical contributors to the mission.

A Process for Capturing CO2 from the Atmosphere

    Authors:
  • Geoffrey Holmes
  • David St. Angelo
  • Kenton Heidel
| 2018

The authors describe a process for capturing CO2 from the atmosphere in an industrial plant. The design captures ∼1 Mt-CO2/year in a continuous process using an aqueous KOH sorbent coupled to a calcium caustic recovery loop. They describe the design rationale, summarize performance of the major unit operations, and provide a capital cost breakdown developed with an independent consulting engineering firm. They report results from a pilot plant that provides data on performance of the major unit operations.
