Objectives: This study examines the association between a country's gun availability and firearm-related terrorism. Methods: Employing data from 140 countries, we assess the possible relationship between a country's rate of suicide by firearm and their count of terrorist attacks involving a firearm through a series of structural equation models. Results: Collectively, we find that there is a positive relationship between gun availability and firearm-related terrorism in 2016 and 2017. However, this result fails our robustness check and is sensitive to the inclusion of the U.S. Conclusion: With important caveats, we believe the U.S. to be unique in terms of both gun availability and terrorism.

目标：本研究考察了一个国家的枪支供应情况与枪支相关恐怖主义之间的关联。方法：利用来自 140 个国家的数据，我们通过一系列结构方程模型评估一个国家的枪支自杀率与其涉及枪支的恐怖袭击数量之间的可能关系。结果：总的来说，我们发现 2016 年和 2017 年枪支可用性与与枪支相关的恐怖主义之间存在正相关关系。然而，该结果未能通过稳健性检验，并且对纳入美国很敏感结论：有重要警告，我们认为美国在枪支供应和恐怖主义方面都是独一无二的。
