So, Russia and Ukraine are still as far apart as ever, with the two warring countries unable to make a significant breakthrough in direct talks in Istanbul.
While there was agreement to exchange more prisoners, Moscow and Kyiv remain deeply divided over how to bring the costly and bitter Ukraine war to an end.
Russia has shown itself to be particularly uncompromising, handing Ukrainian negotiators a memorandum re-stating its maximalist, hardline terms which would essentially amount to a Ukrainian surrender.
Expectations were always low for a Kremlin compromise. But Moscow appears to have eliminated any hint of a readiness to soften its demands.
The Russian memorandum again calls on Ukraine to withdraw from four partially occupied regions that Russia has annexed but not captured: a territorial concession that Kyiv has repeatedly rejected.
It says Ukraine must accept strict limits on its armed forces, never join a military alliance, host foreign troops or aquire nuclear weapons. It would be Ukrainian demilitarization in its most hardline form, unpalatable to Ukraine and much of Europe, which sees the country as a barrier against further Russian expansion.
Other Russian demands include the restoration of full diplomatic and economic ties, specifically that no reparations will be demanded by either side and that all Western sanctions on Russia be lifted.
It is a Kremlin wish-list that, while familiar, speaks volumes about how Moscow continues to imagine the future of Ukraine as a subjugated state in the thrall of Russia, with no significant military of its own nor real independence.
This uncompromising position comes despite two important factors which may have given the Kremlin pause.
Firstly, Ukraine has developed the technical capability to strike deep inside Russia, despite its staggering disparity of territory and resources. The stunning drone strikes recently targeting Russian strategic bombers at bases thousands of miles from Ukraine is a powerful illustration of that. Ukraine, it seems, has some cards after all, and is using them effectively.
Secondly – and arguably more dangerously for Moscow – the Kremlin’s latest hardline demands come despite US President Donald Trump’s increasing frustrations with his own Ukraine peace efforts.
Trump has already expressed annoyance with his Russian counterpart, Vladimir Putin, who he said had gone “absolutely MAD” after massive Russian strikes on Ukraine last week.
But now, Trump himself is under pressure as a cornerstone of his second term foreign policy – bringing a rapid end the Ukraine war – looks decidedly shaky.
There are powerful levers to pull if Trump chooses, like increasing US military aid or imposing tough new sanctions, such as those overwhelmingly supported in the US Senate. One of the key backers of a cross-party senate bill that aims to impose “crippling” new measures on Moscow, Senator Richard Blumenthal, accused Russia of “mocking peace efforts” at the Istanbul talks and in a carefully worded post on X accused the Kremlin of “playing Trump and America for fools.”
It is unclear at the moment how the mercurial US president will react, or what – if anything – he will do.
But the outcome of the Ukraine war, specifically the brokering of peace deal to end it, has become inextricably linked with the current administration in the White House.
The fact that Putin has once again dug in his heels and presented an uncompromising response to calls for peace, may now force Trump to act.
