After all those raised hopes of peace, the second-worst night of air attacks on Ukraine since the war began.
So much for diplomacy, despite Alaska, then the Washington summit.
The Kremlin says it was aiming at military targets, but yet again, the pictures tell a very different story.

He thinks he’s winning this war, and it’s hard to escape the conclusion that he’s using diplomacy to play for time while he carries on beating down the Ukrainians will to win.

The West can wring its hands in condemnation.
But it’s divided between Europe that wants a ceasefire and much more severe sanctions, and President Trump, who, it seems, does not – strangely always willing to sympathise with the Russians more than Ukraine.
He’s back to blaming Ukraine for starting the war, saying earlier in the week that Kyiv should not have got into a war it had no chance of winning.
It is a grotesque perversion of history. Ukraine, of course, had no choice but to fight to defend itself when it was invaded in an act of unprovoked aggression.
Every time the US president has condemned Russia for these kinds of attacks, he has never followed through and done nothing to punish them.

A war that began as one man’s mad idea has, in three and a half years, metastasised into a titanic struggle between east and west, fought increasingly with machines in a dystopian evolution of war.
If President Trump is not prepared to use his power to bring this war to an end, what will another three and a half years of his presidency bring?
It is a chilling question.
