Russian President Vladimir Putin, in an interview to mark 15 years in power, said he has no regrets over Moscow’s 2014 annexation of Crimea as it overturned “a historical injustice.” “I think we did the right thing and I don’t regret a thing,” Putin said of his decision to take back the Black Sea peninsula from Ukraine, during the interview in a state television documentary broadcast on Sunday. “When we defend our (interests), we go to the end,” he said. Explaining the motivation behind Crimea’s takeover, Putin said, it was righting a historic wrong after Soviet leader Nikita Khrushchev transferred the peninsula from Russia to Ukraine in 1954, then only a symbolic move since both were in the USSR.
