Zelensky says he's not sure Putin 'still alive'

During his online address at the World Economic Forum's annual meeting in Davos on Jan. 19, President Volodymyr Zelensky said that he was not "entirely sure" that Russian dictator Vladimir Putin is still alive and makes decisions in Russia.

"I don't quite understand who to talk to and about what. I'm not sure that Russia's president, who sometimes appears against the chroma key is really him," Zelensky responded when asked about the possibility of peace talks.

The chroma key that Zelensky referenced is a visual effects technique used to alter the background around the subject of a video. Some believe that Putin has been using it for his televised public engagements, to appear like he is visiting places while actually staying in safety.

Zelensky emphasized that Ukraine did everything to liberate its territories through diplomacy, but it hasn't worked out.

"Peace negotiations are not yet peace. It should be recognized by both sides," said the president.
