The chilling moment in Russia-Ukraine peace talks - as Putin makes mockery of Trump's efforts to end war

Vladimir Putin made a mockery this week of Donald Trump's efforts to end the war in Ukraine.

Far from punishing him for it, the US president went out of his way to dodge calls to get tough with the Russian leader. Follow latest updates on Ukraine war On Sunday, President Trump called on leaders of both Russia and Ukraine to meet.

He posted: "President Putin of Russia wants to meet on Thursday, in Turkey, to negotiate a possible end to the BLOODBATH. Ukraine should agree to this, IMMEDIATELY." That post let the Russian leader off the hook.

Only the day before, Putin had been ordered by Ukraine's allies, including America, to agree to a 30-day unconditional ceasefire. The Russian president had swerved that demand, suggesting talks instead.

"If the ceasefire is not respected, the US and its partners will impose further sanctions," Trump posted before swivelling and backing Putin's proposals for talks instead. Undeterred, Ukraine's President Volodymyr Zelenskyy accepted the call.

Putin though refused to go, sending officials instead. And yet there was no reprimand from the US president.

Instead, he chose to undermine the talks he had himself called for. "Look, nothing is going to happen until Putin and I get together," he told reporters on Air Force One.

So much for that then. It is what happened in those talks though that should give the US president the greatest pause for thought about Putin's intentions - as it does in Kyiv.

The message they brought was blunt and belligerent, threatening eternal war. "We don't want war, but we're ready to fight for a year, two, three - however long it takes," lead Russian negotiator Vladimir Medinsky is reported to have said.

"We fought Sweden for 21 years. How long are you ready to fight?" Far from offering a compromise, they are reported to have demanded the withdrawal of Ukrainian troops from the four regions they have partially seized by force and the capitulation of another two, just for good measure.

And there was a chilling moment when the Russians are reported to have threatened their interlocutors like gangsters. "Maybe some of those sitting here at this table will lose more of their loved ones," Mednisky said.

Russia is prepared to fight forever. For Sergiy Kyslytsya, Ukraine's deputy foreign minister, that was personal.

Even Fox News, normally slavishly subservient to Trump, is wondering what gives. Its anchor Bret Baier is no Jeremy Paxman, but in an interview last night asked Donald Trump 10 times if he might finally now put pressure on Putin.

The US president ducked and dived, talking about the money he had made in his Gulf tour, Zelenskyy's shortcomings, Biden, and Iran instead. But he did not give a straight answer to the question.

With performances like that, Putin has nothing to worry about. Trump's position though seems increasingly untenable.

Ukraine's European allies though should be alarmed. They threatened Russia with sanctions and retaliation last weekend if he rejected a ceasefire.

He now has. With or without America, will they be good to their word?.
