Don’t Let Ukraine Join NATO

The Costs of Expanding the Alliance Outweigh the Benefits
As the war in Ukraine grinds on, policymakers and pundits, including Ukrainian President Volodymyr Zelensky and the former U.S. ambassador to NATO, Ivo Daalder, are pushing for NATO to offer Ukraine what French President Emmanuel Macron calls “a path toward membership” after the conflict concludes. This is not just show. Ukraine’s membership aspirations will now be a central topic of debate at NATO’s summit next week in Vilnius, with Ukraine arguing—as its former defense minister Andriy Zagorodnyuk wrote recently in Foreign Affairs—that it “should be welcomed and embraced” by the alliance. The way in which this issue is settled will have serious consequences for the United States, Europe, and beyond.
