MOSCOW (AP) — Russian President Vladimir Putin has responded to U.S. President Joe Biden’s description of him as a killer by citing America’s own past and current problems. Biden was asked in an interview whether he thought Putin was a killer and replied, “I do.” Asked about that remark, Putin pointed at the U.S. history of slavery, slaughtering Native Americans and the atomic bombing of Japan in World War II.. He said this painful legacy still weighs on the country. Biden has taken a tough stance on Russia, contrasting with the approach of former President Donald Trump, who avoided direct confrontation and frequently spoke about Putin with approval.
