Unified heavyweight champion Oleksandr Usyk offered one of his boldest indictments against the Russian invasion of Ukraine to date.

The WBO, WBA, IBO, IBF beltholder from Ukraine did not mince words in a recent video that was uploaded on his Instagram page, taking aim at Russian president Vladimir Putin as his country’s war on Ukraine approaches its one-year anniversary.

“You attacked Ukraine, supposedly to protect Russians who do not want your protection,” Usyk said (subtitles provided by Anton Gerashchenko). “The same way you attacked Czechoslovakia years ago you came to other cities and to Georgia, et cetera. You come everywhere with protection, but you do not protect Russians in Russia itself. You do not protect them in any way. You are fighting against fascism and nazism, which does not exist.”

Russia first attacked Ukraine last year, on Feb. 24. Usyk, who at the time was in England to carry out negotiations for a rematch with Anthony Joshua, put his boxing career on hold and returned to his country to partake in the territorial defense battalion. Usyk later decided to square off against Joshua and received permission from his government to do so. Usyk wound up defeating Joshua on points in Jeddah, Saudi Arabia on Aug. 20.

“You are the Third Reich in all the variety of its manifestations,” Usyk continued, referring to Russia. “What Hitler didn’t do, your president continues to do. Can you imagine? Yes.”

Usyk, the former undisputed cruiserweight champion, is now in talks to face WBC titlist Tyson Fury of England for the undisputed heavyweight crown.

On Monday, BoxingScene.com’s Keith Idec reported that if an offer to stage the fight in Saudi Arabia does not come soon, the organizers will look to place the fight at Wembley Stadium in London. Fury is promoted by Top Rank’s Bob Arum and Queensberry’s Frank Warren. Usyk is backed by K2 Promotions. Arum said if the fight happens in England, Usyk may have to settle for a lesser percentage of the financial pot because Fury would be the clear-cut driver of the revenue.
