    Abstract This study explores the political-economic determinants of military strategy during civil war to explain the intensity of suffering that certain conflict zones and their inhabitants suffer due to aerial bombing and landmines. Adversaries seeking post-war rents consider distinct consequences of weapons use in the target society: bombing causes instantaneous destruction, whereas landmines cause persistent but fading negative externalities on human activities, such as labor. Thus, it is expected that economic rents with different characteristics are associated with the use of different types of weapons because the benefits derived from these rents after the conflict vary. By focusing on the nature of economic rents available in conflict zones, this study demonstrates that aerial bombing is more likely when the targeted territory relies economically on renewable resources and industries such as agriculture, whereas landmines are more likely to be used in territories endowed with perishable resources such as gemstones. An empirical analysis utilizing newly compiled geo-coded data on the locations of US airstrikes and landmine contamination during the Cambodian Civil War finds strong positive associations between agricultural productivity and the number of airstrikes, and between the proximity to large gem deposits and landmine contamination, holding major tactical variables constant. The results suggest that societies' economic structures have a sizable effect on the manner in which adversaries fight a war and, therefore, affect how people suffer from it.

    Despite widespread concern over heated diplomatic debates and growing interest in public diplomacy, it is still incompletely understood what type of message is more effective for gaining support from foreign public, or the international society, in situations where disputing countries compete in diplomatic campaigns. This study, through multiple survey experiments, uncovers the effect of being silent, issuing positive justification, and negative accusation, in interaction with the opponent's strategy. We demonstrate that negative verbal attacks work and undermine the target's popularity as they do in electoral campaigns. Unlike domestic electoral campaigns, however, negative diplomacy has little backlash and persuades people to support the attacker. Consequently, mutual verbal fights make neither party more popular than the other. Nevertheless, this does not discourage disputants from waging verbal fights due to the structure similar to the one-shot prisoner's dilemma. We also find that positive messages are highly context-dependentthat is, their effects greatly depend on the opponent's strategy and value proximity between the messenger and the receiver.
