Polarization in the USA has been on the rise for several decades. In this context, few observers expect politics today to stop "at the water's edge," as the old cliché goes. But key questions about the relationship between polarization and US foreign policy remain to be fully answered. To what extent are American ideas about foreign policy now polarized along partisan lines? How is polarization changing the foreign policy behavior of the US Congress and President? And how is polarization altering the effectiveness of US foreign policy and influencing America's role in the world? In this introductory article to our special issue "Domestic Polarization and US Foreign Policy: Ideas, Institutions, and Policy Implications," we provide an overview of key debates and existing knowledge about these questions, highlight important new findings from the contributions to the special issue, and suggest avenues for further research on this increasingly important topic.
几十年来，美国的两极分化一直在加剧。在这种背景下，很少有观察家认为如今的政治会像那句老套话所说的那样“在水边止步”。但关于两极分化与美国外交政策之间的关系，一些关键问题仍有待全面解答。美国在外交政策上的观点如今在多大程度上沿着党派路线两极分化？两极分化如何改变美国国会和总统的外交政策行为？两极分化又如何改变美国外交政策的有效性并影响美国在世界上的角色？在我们关于“国内两极分化与美国外交政策：理念、制度及政策影响”特刊的这篇介绍性文章中，我们概述了关于这些问题的关键辩论和现有知识，突出了特刊各篇文章的重要新发现，并为进一步研究这个日益重要的话题提出了途径。
