Russian President Vladimir Putin is being pushed "further into a corner" by falling oil prices, leaving him little option but to continue his aggression toward Ukraine and confrontation with the West, Eurasia Group President Ian Bremmer told CNBC on Tuesday.
Putin has "gone all-in on an anti-U.S., must-keep-Ukraine nationalist engagement," Bremmer said on "Squawk Box." He said it's "completely inconceivable" for Putin to back down.
"This is what is behind all his approval ratings. It's behind who he now is as a leader," Bremmer said, adding that capitulation would "erode a lot of his power."
Russia's currency and economy are crumbling along with oil prices, the country's main export and revenue source. On Monday, the ruble suffered its worst one-day decline since 1998, and it looks like Russia's economy will tip into recession next year.
