Biden's 'crazy SOB' remark on Putin not likely to offend — Kremlin spokesperson

"This is a huge shame for the country itself,” Peskov told Zarubin.

“I mean for the United States of America. If the President of the country uses such language, it should be a shame."

Peskov further claimed Biden's statement was motivated by "domestic political interests" and, using the most obvious cliché possible, was “probably some kind of attempt to look like a Hollywood cowboy.”

“We have a crazy S.O.B. that guy, Putin,” Biden told those gathered at a San Francisco fundraiser.

“And we always have to be worried about a nuclear conflict. But the existential threat to humanity is climate.”

This isn't the first instance of Biden's harsh words towards Putin, having previously accused him of responsibility for Alexei Navalny's death and labeling him a "pure thug" and "murderous dictator" amid the Russian full-scale war against Ukraine.
