Russia bombarded Ukraine’s second-largest city with massive strikes in the early hours of Saturday, its mayor said, one night after Moscow carried out one of the war’s largest aerial assaults on Ukraine.

Following Ukraine’s recent drone assault on Russia, where Ukraine used $300 drones to take out $100+ million Russian bombers, questions mount about what’s next for the Ukrainians. Eurasia Group and GZERO Media president and founder Ian Bremmer joins Katy Tur to break down why “we don’t see any possibility of [the war] ending anytime soon.

US President Donald Trump said it might be necessary to let Ukraine and Russia “fight for a little while” before brokering a peace deal and suggested he might be willing to implement fresh sanctions on both countries if he determined the conflict wasn’t going to end.
