Obama's Complex Relationship with Russia and Anti-Democratic Leaders.

A senior Ukrainian official has criticized former US President Barack Obama for not admitting critical mistakes in his administration's Russia policy, including Moscow's illegal 2014 annexation of Crimea. Obama defended his administration's reaction to the annexation in a recent interview, arguing that the situation in and around Russia had changed since 2014. Both the US and the EU imposed sanctions on dozens of Russian and pro-Kremlin Ukrainian officials after Russia illegally annexed Crimea in 2014, but they faced criticism for their overall ineffectiveness.
