14. Viktor Yanukovych, Ukraine (2014)
In 2014, during Ukraine’s Euromaidan movement, the United States provided support to protesters advocating for closer ties with the European Union. This assistance included diplomatic backing and, reportedly, non-lethal aid. The movement led to President Viktor Yanukovych’s ouster in February 2014. His removal significantly strained U.S.-Russia relations, contributing to Russia’s annexation of Crimea and the onset of the conflict in Eastern Ukraine. (reuters.com)
