Ian Bremmer shares his insights on President Biden's Afghanistan speech, the Afghan refugee crisis that will follow the Taliban takeover, and booster shots in the US.

What did you think of President Biden's speech on the Afghan withdrawal?

Two things. One, I thought he made a very compelling case for why the United States needed to leave when we did. The reduction in US troops that already happened under Trump, the strengthening of the Taliban, the difficulty of any expansion, I get all of that, but it was, listening to it as if the last 72 hours hadn't happened. He said that, "this is on me, the buck stops with me," but didn't talk really about any of the serious failures and how they could have occurred on the ground in Afghanistan. And there's a lot to answer for there. So I certainly don't give high marks to the speech, if I'm being honest with you. I'm doing my best.
