From the Telegraph / Yahoo!News:
"Putin is using a classic Russian negotiating tactic to delay a ceasefire
Vladimir Putin had three options: accept Ukraine’s ceasefire offer, but surrender momentum on the battlefield; reject it and risk antagonising Donald Trump; or try to drag things out so he can continue fighting as long as possible.
He has chosen option three.
By praising the US president and the idea of stopping the war, he hopes to stay in Mr Trump’s good books. But his immediate raising of “nuances” to discuss should be a red flag.
This is a classic Russian negotiating tactic – as any diplomat who has been in a room with Sergei Lavrov will tell you.
By breaking every proposal down into an infinite number of constituent parts, he will attempt to appear co-operative while playing for time, bogging down the talks, and trying to use facts on the ground to squeeze out the maximum possible concessions.
So Mr Trump and his cabinet now face a test of nerve and credibility.
They could ignore Mr Putin’s excuses about “nuances” and demand he order a ceasefire immediately – it is, after all, entirely in his power to do so.
That would mean showing the kind of impatience and coercion they applied to Volodymyr Zelensky.
This could include unleashing the “bone-breaking” sanctions package Senator Lindsey Graham has threatened if Russia does not comply – in other words, smacking the Kremlin’s “donkey” face with a two-by-four, as Gen Keith Kellogg, Donald Trump’s special envoy, boasted to have done to Ukraine.
Mr Putin is far from invincible. He has been losing upwards of 1,000 soldiers a day, his economy is overheating, and he’ll face serious domestic headaches by 2026 on the current trajectory.
If the Americans get tough, he will probably fold.
However, they could get drawn into Putin’s painstaking discussion of the details. That would be to repeat mistakes made by successive US presidents going back to Barack Obama.
Putin already gave a sense of the cards he will seek to play on in those talks.
He claimed to have Ukrainian troops surrounded in Kursk and said they had no way out but death or surrender...
He also demanded that Ukraine be prevented from mobilising troops during the proposed 30-day truce or redeploying weapons to the front. That would effectively deny Ukraine the opportunity to defend itself from renewed Russian attack.
This will give Ukrainians deja vu. In 2014 and 2015, Mr Putin twice used encirclement of Ukrainian troops to force punishing ceasefire deals on his own terms.
Last time, it was the Organisation for Security and Co-operation in Europe that provided unarmed observers to diligently count explosions and measure the size of fresh craters. They were unable to stop the war, because they were constantly deceived.
In 2014, for example, Russia made a great show of agreeing to host OSCE observer missions at its border checkpoints to make sure no troops or weapons were crossing into Ukraine.
In fact, Russia confined the observers to the official customs post in accordance with their mandate, while driving tanks and troops – including the missile launcher that shot down MH17 – into Ukraine across a field just a few miles away.
I know, because I saw them do it.
Maybe, in defiance of all expectations, the fighting will cease this weekend.
Otherwise, Putin will try to lure the Americans into open-ended diplomacy while using force to wring maximalist concessions and lay the groundwork to blame Ukraine if – when – the talks (or the ceasefire, if things get that far) collapses.
The ball is now in Mr Trump’s court."
