Biden brands Putin a ‘crazy SOB’

Joe Biden has branded Vladimir Putin a “crazy SOB”, warning there is always the threat of nuclear conflict.

Initially addressing the challenges of climate change, the president said: “This is the last existential threat. It is climate. We have a crazy SOB like that guy Putin and others and we always have to worry about nuclear conflict, but the existential threat to humanity is climate.”

Mr Biden’s verbal attacks against Putin have sharpened at the White House and on the campaign trail.

Last week, he blamed the Russian leader and “his thugs” for the death of Alexei Navalny – which the Kremlin denies.

The US president has a tendency to go off script during election fundraisers and in recent months has made digs at the Chinese government, the Republican Party and Israel.
