Take a look at a map of the NATO countries today and compare it to one from 1989. It's a remarkable change. And what once seemed far-fetched is now close to becoming reality. That is, almost all of Europe will belong to NATO right up to Russia's borders. But Finland's and Sweden's applications to join the alliance, prompted by Moscow's invasion of Ukraine, may be blocked by NATO's only Asian member, Turkey. In this episode, historians Timothy Sayle and Howard Eissenstat break down Europe's changing geopolitics. Learn why Sweden and Finland are shedding decades of non-alignment and why Turkey, one of NATO's earliest members, is moving closer to the Kremlin.
