Thirty years ago, in early December 1994, at a security summit in Budapest, the United States, United Kingdom, Russia, and Ukraine signed a memorandum in which Kyiv agreed to eliminate all nuclear weapons left on its territory after the collapse of the USSR. In exchange, the other signatories offered assurances to refrain from the threat or use of force against Ukraine's territorial integrity or political independence. Events would prove the Budapest Memorandum to be worth less than the paper it was printed on. Thirty years later, Russia has invaded Ukraine and occupies much of its eastern regions. The war has been devastating, killing tens of thousands of soldiers on both sides. In this episode, historian Michael Kimmage looks back at the empty assurances of the Budapest conference, which were made at a time of great optimism and even cooperation among former foes. Kimmage also contends that today's war is a world war insofar as it has expanding global repercussions and is attracting the involvement of non-European countries.
