And what does it actually mean to kick China out of Latin America?

David, just to step back here for a moment, can you help me understand how the taking up of the Monroe Doctrine, this new muscular posture that we're going to be taking in Latin America with new military deployments, isn't that out of step with the original understanding that I think a lot of us had of America first as this policy of isolationism?

So what makes this worth it to Trump?

Like, why risk pulling MAGA apart, as you said, over this?

What does the U.S.

actually get out of reasserting its dominance in this really aggressive way?

But how is declaring a sphere of influence coherent with America first?

I mean, you could see how leaving the rest of the world to its own devices jives with an isolationist's view of how to engage with the world.

But help me make sense of the internal logic of declaring American predominance over an entire swath of the globe.

What do you mean by that?

David, we've been talking about this document as a major pivot and a reorientation of American foreign policy.

But I have to ask, as someone who has spent so much time covering American leaders and American actions across the globe —

How enduring is the shift that we're seeing represented here?

Does it last beyond this president?

David, thanks so much.

We'll be right back.

Here's what else you need to know today.

On Thursday afternoon, Senate Republicans blocked a Democratic bill to extend federal health care subsidies, making it all but certain that insurance costs will surge for millions of Americans by the end of the year.

The bill would have extended the subsidies for the Affordable Care Act by three years, a rallying cry for Democrats and their central motivation for shutting down the government for 43 days.

But even with four Senate Republicans backing the measure, Democrats fell short of the 60 votes they needed to pass it.
