The archbishop of Chicago, Cardinal Blase Cupich, as well as Cardinals Robert McElroy of Washington D.C., and Joseph Tobin of Newark, New Jersey, agreed to their first ever joint interview. Their candor surprised us, about the new pope and what they're hearing in the pews.

But in a Palm Sunday homily, he appeared to reference the religious language Defense Secretary Pete Hegseth, who is Christian but not Catholic, often uses to frame the war.

Pope Leo warned that Jesus, quote "does not listen to the prayers of those who wage war."

Norah O'Donnell: Is this a just war?

Cardinal Robert McElroy: No, in the Catholic teaching this is not a just war. The Catholic faith teaches us there are certain prerequisites for a just war. You can't go for a variety of different aims. You have to have a focused aim, which is to restore justice and restore peace. That's it.

Norah O'Donnell: Iran has been the chief exporter of terror. Is there no scenario in which preventing that can be a just war?

Cardinal Robert McElroy: It's an abominable regime, and it should be removed. But this is a war of choice that we went to, and I think it's embedded in a wider moment in the United States that's worrying, which is this: We're seeing before us the possibility of war after war after war.

This past January, Cardinal Tobin called Immigration and Customs Enforcement - or ICE - a "lawless organization."

Norah O'Donnell: Cardinal, those are strong words to call ICE "a lawless organization."

Cardinal Joseph Tobin: Yeah.

Norah O'Donnell: Why did you do that?

Cardinal Joseph Tobin: I didn't say that they were people without law. But when people act in this way, when they have to hide their identities to terrify people, when they can actually violate other guarantees of our Constitution and Bill of Rights, well I think somebody's got to call that out and I'm not the only one.
