Last week, Ukrainian President Volodymyr Zelensky was on an overnight train.
According to a person present, he was in a gloomy mood.
He was on his way to meet the British Prime Minister in London and European Union leaders at a summit in Brussels,
where he was seeking reassurance from Ukraine's European allies that they were still standing by him.

And while he was on this train, he and his inner circle of advisors received
the news that for the second time in two days, Russian missiles had landed on Kiev, had hit energy infrastructure,
that is power plants, with no warning, without the usual warning from U.S.
Intelligence that there had been missile launches.
These warnings from U.S.
Intelligence have been essential for Ukraine.
They allow civilians to take cover and give the military a chance to try to intercept Russian missiles.
And that wasn't the only news involving American assistance that made Zelensky worry.
A few hours later, Zelensky received another message, namely from Ukraine's military, saying
that their military Starlink terminals were suddenly not working at full speed.
That is, their drones were losing connectivity if they were flying over 100 miles an hour.
And that led to the failure, with no warning,
of some of their strike missions against Russian forces in occupied parts of Ukraine.
Taken together, these developments signaled to Zelensky that the U.S.
Was turning its back on Ukraine.
