Putin thinks he's winning Ukraine war - and it's now hard to escape one conclusion

After all those raised hopes of peace, Ukraine has been hit by the second-worst night of Russian air attacks since the war began.

So much for diplomacy, despite the Alaska summit, then the Washington DC meeting. The Kremlin says it was aiming at military targets, but yet again, the pictures tell a very different story.

The Russian president 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. And at the moment, no one is stopping him Ukraine is hitting back, particularly at Russia's oil installations, more of them going up in thick black smoke, after being hit by long-range Ukrainian drones.

It is taking a heavy toll on Putin's 'Achilles heel', but on its own, analysts don't expect it will be enough to persuade him to end this war. 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. More worryingly for the Ukrainians, the Russians are getting the upper hand in the drones war, taking Iranian technology and souping it up into faster-moving drones that the Ukrainians are having increasing difficulty bringing down.

They expect as many as a thousand drones a night coming their way by the winter, and many, many more innocents to die. Next week, Putin will join Chinese and North Korean leaders in a summit in Beijing, both supporting his war in Ukraine.
