This week, America switched sides.

Ukraine is out.

Russia is in.

President Trump has blamed Ukraine for starting the war that was started by Russia,

and America's traditional European allies are in a state of shock.

Tonight, Trump's stunning pivot to our Putin and what it means for America's role in the world.

Next.

Good evening and welcome to Washington Week. There was a time when America could be counted

on to support the goals of the NATO alliance. And that time was technically at least last week.

This week, America's allies in Europe,

partnerships that were formed in the aftermath of World War II,

have been left wondering if they'll ever be able to count in America again.

And they're not the only ones.

From East Asia to the Middle East, from Panama to South Africa,

leaders are scrambling to understand Trump's wishes and desires.

I'll scramble tonight as well with my guests

Peter Baker, the Chief White House correspondent at the New York Times. Susan Glasser is a staff

writer at The New Yorker. And Jonathan Lemire is a contributing writer at The Atlantic, as well as

co-host of Morning Joe on MSNBC. Thank you all for joining me. We have news just as we were coming on set.

President Trump has fired the chairman of the Joint Chiefs of Staff, General CQ Brown, Air Force

General, four-star General, second black chairman of the Joint Chiefs of Staff. Jonathan, surprising that he would fire him?

No, not at all.
