In the coming week, the expired Black Sea grain deal alarms global food supply chains.

Spain holds snap parliamentary elections, and the annual Comic-Con event feels the heat of Hollywood strikes.

It's July 20, 2003, in time for the world next week. I'm Bob McMahon.

And I'm Carl Ann Robbins.

Carla, we're going to begin with Ukraine and Russia for all sorts of reasons, but particularly because of the way the week started, which is Russia exiting the Black Sea grain deal.

As we've discussed before, the deal created a safe corridor for Ukrainian grain to be exported.

And this is grain that plays a vital role in global food security.

But how should we understand Vladimir Putin's motives in taking this step?

And we've already seen the subsequent heavy shelling of the ports from which that

grain was delivered. Bob, you know, we've talked about this before. Putin has played chicken

with the deadlines on this initiative since it was signed a year ago. And we don't know,

is he having a brief hissy fit or is he seriously walking away this time? It's really hard to

tell. But the people I've been talking to say

that he's been rebuffing any attempt even to discuss his demands, both Turkey's Erdogan

and UN Secretary General Gutierrez, who brokered the agreement, reached out last weekend as the clock

was ticking down, and Putin, I understand, refused to even take their calls. And right now,

you know, Moscow is sounding especially belligerent. The Russian defense ministry is warning that

any ship sailing to Ukrainian black seat ports will be considered to be involved in the Ukrainian

conflict on the side of the Kiev regime. And Russian missile strikes this week have targeted

the ports, Odessa, Chornamorsk, destroying grain stocks and port infrastructure.

The Russians say these are retaliatory strikes after their courage bridge.

You remember that bridge that Putin inaugurated.
