Since 2003, the Proliferation Security Initiative (PSI) has grown from a small collection of like-minded states into a widely accepted, and increasingly institutionalized, counterproliferation effort. However, while the PSI has evolved, the literature around it has stagnated—and disserves ongoing debate by adopting a framework that is both ahistorical and binary. Building on the author’s 2007 paper, this article assesses the past 15 years’ critiques, and argues that the PSI paradoxically reinforces our prevailingly mare liberum regime at the same time that it challenges established navigational freedoms such as the right of innocent passage.

PSI是一种共享产品：防扩散安全倡议如何既挑战又加强了普遍的自由母马政权

自2003年以来，防扩散安全倡议（PSI）已从一小撮志同道合的国家发展成为被广泛接受且日益制度化的反扩散努力。但是，尽管PSI不断发展，但围绕它的文献却停滞了，并且通过采用既是历史性的又是二进制的框架来避免正在进行的辩论。本文以作者2007年的论文为基础，评估了过去15年的批评，并认为PSI在挑战既定的航行自由（如无害通过权）的同时，反而强化了我们普遍的母马自由政权。
