WASHINGTON, May 10. /TASS/. US President Joe Biden has said Russia may have no way out of the crisis in Ukraine and he’s trying to understand what to do about it.

Speaking at a Democratic Party event, he said, Russia "doesn't have a way out right now, and I'm trying to figure out what we do about that," Reuters reported.

Biden called Russian President Vladimir Putin a very calculating man. The US president said Putin had thought he would break up NATO and break up the European Union.

On February 24 Russian President Vladimir Putin announced a special military operation in response to a request for help by the heads of the Donbass republics. He stressed that Moscow had no plans of occupying Ukrainian territories, but aims to demilitarize and de-Nazify the country. The US and its allies retaliated by imposing sweeping sanctions on Russia and started arms supplies to Kiev.
