Welcome to Potsy of the World. This is Tommy Vittor on the line all the way from New Jersey.

The exotic location of Princeton, New Jersey is Ben Rhodes. Ben, how you doing?

Good, man. I just spoke here at Princeton. Saw a lot of world-os in the audience.

That's fantastic. A lot of Obama loves it.

For those of you in DC, I'll be at both American University and Georgetown on Thursday. So come check that out.

All right, check that out. Later on in the show, I talked to Cuba expert, Marguerite Hemenez, about all the ways Donald Trump has rolled back the historic changes to US-Cuba policy that you negotiated Ben.

And I want to ask you about that a little bit later. But first, I want to start with Sri Lanka, North Korea, testing more weapons, some news out of China.

Trump finally getting his visit to the United Kingdom. The Armenian Genocide Remembrance Day, a major election in Ukraine. So it's a packed one, as per usual.

Lankanon. All right. Let's start with Sri Lanka. So on Easter Sunday, there was a series of horrific bombings at churches, hotels, restaurants in Sri Lanka, anywhere where there were Westerners.

The bombers used high-grade explosives. They were coordinated and deadly attacks. The death toll, I believe, is at 321 people as of this recording.

ISIS is taking credit for it. They said it was designed to target Christians, Westerners, the reports that the Sri Lankan government had some intelligence warning them of the attack, but actually didn't do anything to prevent the attacks, which is troubling and will likely lead to major changes.

There are also reports that some of the attackers had traveled to Syria. Some have suggested it was a response to the New Zealand Mosque shooting, which I don't know maybe they said that, but that seems ridiculous to me.

ISIS doesn't need a reason to kill innocent people. The Sri Lankan government has taken some steps to impose a curfew and block social media networks. But Ben, I guess I'm trying to figure out what this tells us about ISIS.

I've talked recently about whether or not ISIS has been defeated in Iraq and Syria, but to me this says we have a lot more work to do globally to stop the threat.

I mean, first of all, it's an awful tragedy in a country that had recently climbed out of a brutal civil war, so compounding that fresh wound in Sri Lanka. I think what it tells us if it is ISIS and the indications are that there's some role here, is that this is the direction that ISIS will move in.

We've talked about the fact that as they can no longer hold territory in Syria and Iraq, they'll probably more into a more traditional terrorist organization, albeit a particularly lethal one.

And that they will probably seek out, with this tells us that they may seek out places where they see vulnerabilities.

So countries like Sri Lanka that may seem like easier targets, you know, than say a Western country with advanced CT capabilities. And that may be what we're looking at.

An ISIS that more is back into sponsoring these types of attacks that is opportunistic and picking places where they see vulnerability.

Interestingly, the Sri Lankan government has been badly divided. The Prime Minister is, you know, a political adversary at the Defense Minister.

And so one of the reasons why information might not have been shared is that you have a rivalries in this government.

And so it looks like they found the soft target to go after. And again, it may seem that ISIS will shift to that type of targeting, and particularly targeting it seeks to pit Muslims against Christians or against people of different religions.
