It was a piece of news so obscure and implausible that I missed it when it first surfaced last month. The news was that the Russians are going to put hypersonic nuclear missiles into Nicaragua and terrify the Americans into backing down over Ukraine. Or kill them all if they don't.
"If American missile systems can nearly reach Moscow from Ukrainian territory, it's time for Russia to roll out something powerful closer to the American 'city on a hill'," said Olga Skabeyeva on the news show on Rossiya-1, the most popular Russian TV channel.
The usual crew of panelists hugged themselves with delight at the idea of American cities being blown away. "Objects like the city of New York, a good city, but it would be gone. Completely gone with one rocket," said one.
Then they rambled on about how the Cuban missile crisis of 1962 had brought the Americans to their senses, and how Russian missiles in Nicaragua might bring Americans to their senses again. They will give in before they really get hurt.
As a substantial majority of the Russian TV audience watches the show, that's the news ordinary Russians are getting. But if these people really represent the Russian elite's views of what is possible and necessary, then we're all in trouble. Nuclear war is at hand.
Are there really Russian generals and senior foreign ministry officials who think that "American missile systems can nearly reach Moscow from the Ukrainian territory"? If you mean American nuclear missiles, then of course not.
The US has given non-nuclear battlefield missiles to Ukraine, but it has restricted the ammunition to types that cannot reach any significant distance into Russia. There are no American troops in Ukraine, and no nuclear weapons in Ukrainian hands.
The business about moving American nuclear missiles "closer" to Russia is complete tripe: they are just as lethal from where they are now. Russian generals and diplomats are not stupid: they know that American nuclear weapons systems have been able to reach Russia from the US homeland or any of the world's oceans since the 1960s.
The difference between Cuba in 1962 and Nicaragua today is that "close" still meant something in 1962, when the US already had intercontinental ballistic missiles that could reach the old Soviet Union, but Russia had no long-range ballistic missiles that could hit American cities yet.
The Russians sneaked some shorter-range nuclear missiles into Cuba to even things up, but the Americans spotted them, imposed a blockade, and threatened to invade Cuba. Moscow pulled its missiles out, and everybody lived grumpily ever after.
Nowadays, both Russia and the US have ample weapons that they can fire at each other from their homelands. "Closer" no longer confers any advantages. Besides, Nicaragua has not said it will host Russian nuclear weapons.
Nicaraguan President Daniel Ortega published a decree last month authorising small numbers of troops from Russia, the US or other Central American countries to deploy to his country for a limited time.
Mr Ortega was a Marxist in the 1980s. After the Nicaraguan revolution triumphed, he got Soviet help, and US president Ronald Reagan financed a guerilla/terrorist movement in an unsuccessful attempt to bring him down, but that was long ago.
Now, Mr Ortega is just another dictator like Mr Putin. He rigs elections, jails the opposition, and treats the state budget as his private income. Nicaragua is broke, so Mr Ortega is happy to take Russian money, but he's probably not stupid enough to let the Russians bring missiles in.
Russia's much-hyped hypersonic missiles are irrelevant anyway, since "hypersonic" missiles are only useful if a country has good anti-missile defences.
In fact, nobody has good missile defences, so, they make little difference strategically. Dumb missiles with some terminal guidance work just fine.
The rational conclusion, therefore, is that this is all just propaganda blather by ignorant Russian TV pundits, but a warning. I predicted that Russia would not invade Ukraine because it would be utterly stupid to do. I am still assuming that Russian leaders are rational, but now I have some doubts.
