Welcome to The World in Ten.
In an increasingly uncertain world, this is The Times's daily podcast dedicated to global security.
To date with me, Tom Noonan and Stuart Willey.
Ukraine is mourning the dozens of people killed in a Russian missile strike in Sumi in the east of the country.
It was the deadliest attack so far this year,
prompting horror at graphic images of civilians killed on their way to church and widespread condemnation from world leaders.
But for Donald Trump, the strike was instead a mistake and he blamed Vladimir Zelensky for starting the war.
And that's worrying many in Ukraine,
including a senior MP who says it shows someone in Trump's entourage is pushing Russian narratives.
To dig into this, and what it all could mean for the prospects of peace,
we're joined by James Nixie, the head of the Russia Eurasia Programme at Chatham House.
James,
does this strike on what appears to be clearly civilian targets show something is changing in how Russia is conducting this war?
It shows a very little is changing in how Russia is fighting the war.
Russia's modus operandi is indeed pretty much a scorched earth policy.
If it can't control Ukraine, it will wreck it.
And that is precisely what it's doing.
It is failing to win, really, even at the diplomatic table right now,
although we can go into that in more detail, but it's certainly failing to win militarily, as it initially wanted.
That leaves Russia to exert its military superiority, which it still has.
