von Borzyskowski and Vabulas’ Review of International Organizations 14(2):335-366 (2019) pioneering research explores why states withdraw from intergovernmental organizations (IGOs). Contrary to popular belief, the research finds that IGO withdrawal has little to do with increased nationalism and instead is largely driven by geopolitical reasons and democracy levels both within the state and organization. In this study, I test von Borzyskowski and Vabulas’ empirical analysis by the introduction of an alternative measure of leader nationalism that more closely matches their theoretical argument. With this alternative nationalism measure, I find strong evidence consistent with popular belief: nationalism is a key driving force for IGO withdrawals across space and time.

von Borzyskowski和Vabulas的《国际组织评论》 14（2）：335-366（2019）的开创性研究探索了国家为何退出政府间组织（IGO）。与普遍的看法相反，该研究发现，政府间组织的撤离与民族主义的增强无关，而是很大程度上受国家和组织内部的地缘政治原因和民主水平驱动。在这项研究中，我通过引入一种与民族理论更接近的替代性领导民族主义措施，来检验冯·博尔斯基斯科夫斯基和瓦布拉斯的实证分析。通过这种替代性的民族主义措施，我发现有力的证据与普遍的信念一致：民族主义是政府间组织撤离时空的关键动力。
