It’s been a week. In just seven days, former President Trump miraculously survived an assassination attempt, picked J.D. Vance as vice presidential candidate, and delivered the longest acceptance speech in history at the GOP convention in Milwaukee (he also holds the record for the second and third longest acceptance speeches). Oh, and through it all, the Democratic party continued its tailspin into crisis as internal clamor grew for President Biden to step aside. Amazing when the afterthought for the week is whether the sitting president will remain on the ticket for an election just months away. But that's where we are.

On GZERO World, Ian Bremmer reflects on this pivotal week in US politics and welcomes back media journalist and former CNN show host Brian Stelter on the show alongside Vanderbilt political historian Nicole Hemmer. “We're living in a period of escalating political violence and social and political instability,” Hemmer tells Bremmer. “That was true in the late 1960s and early 1970s, and I think that it's true today."
