Will Biden's reversal to allow F-16s to Ukraine be a game-changer? What is holding up a debt ceiling deal? Will the EU's lawsuit against Meta lead to a data-sharing agreement with the United States? Ian Bremmer shares his insights on global politics this week on World In :60.

Will Biden's reversal to allow F-16s to Ukraine be a game-changer?

Well, Putin says it is. Says that that would absolutely be a line that would be crossed and be irreversible. Of course, he said that about a bunch of things, and his credibility in a response to NATO providing defense to Ukraine has been significantly eroding over the last year. Of course, we also see not just F-16s, but we see Ukrainian armored troop carriers suddenly five miles deep in Russian territory, in Belgorod. The Ukrainians say it wasn't them, but they're very happy to embarrass Putin over that. Look, a lot of things that would've been seen as red lines six months ago now are not. Of course, that's good for the Ukrainians, but it also does mean that the tail risk dangers of this conflict are also going up.
