Ukrainian President Volodymyr Zelensky says Ukraine's partners in Europe have not given him sound guarantees that they will defend Ukraine in the case of a fresh offensive by Russia.
"I continue to pose this critical question to all our partners and thus far, the answer remains elusive a definitive and straightforward response yet," he told reporters on midweek.
These remarks follow a day after Britain and France signed a statement of purpose on stationing forces in Ukraine if a peace deal to conclude the conflict with Moscow is finalized.
However, comprehensive defense assurances have not been agreed. The United States, which has been leading efforts to end the invasion, was reported to have abstained from signing such a commitment at talks in Paris on Tuesday.
Details of the Paris Talks
After the Paris talks, which involved some three dozen nations that comprise the so-called Coalition of the Willing, British PM Keir Starmer said the two nations would "establish military hubs across Ukraine" to deter future invasion, while French President Emmanuel Macron subsequently indicated a significant number of soldiers may be sent.
Allies proposed that the United States would assume a leading role in overseeing any ceasefire. But the central sticking point of ceding land that Ukraine is being pressured to offer to Russia as a component of the settlement terms are still being discussed.
Moscow has thus far remained silent on the declaration made in the city of Paris.
Russian President Vladimir Putin initiated a comprehensive military assault of Ukraine in the early months of 2022, and Russian forces now occupies about 20% of Ukraine's land.
Zelensky's Shifting Tone
Sir Keir described the joint statement as "an essential component of our dedication to support Ukraine for the foreseeable future".
He added: "It paves the way for the juridical structure under which British, French and partner forces could function on Ukraine's territory, protecting Ukrainian airspace and waters, and regenerating Ukraine's military for the years to come."
Zelensky hailed that agreement as a "huge step forward".
Twenty-four hours afterward, however, he seemed more cautious.
"I perceive the determination, the political resolve, and that the allies are prepared, and the allies are willing to give us robust economic measures, powerful defense assurances," he said when asked if nations in Europe would defend Ukraine.
"But as long as we lack such binding security pacts - formally ratified, supported by parliaments, backed by the U.S. Congress - this crucial issue remains unresolved. And even if they do, you must ultimately depend first and foremost on your own strength."
Unresolved Issues and Ongoing Conflict
Negotiations in Paris were also notable owing to the presence of envoys from former President Trump's administration, Steve Witkoff and Jared Kushner.
Witkoff said the allies "mostly completed" their work on agreeing security protocols.
Last week, Zelensky said a settlement was "90% ready".
Questions of land and security guarantees have been at the center of outstanding matters for diplomats.
The Russian leader has consistently stated that Ukrainian troops must withdraw from all of Ukraine's eastern Donbas or Russia will seize it, dismissing potential concessions over how to conclude hostilities.
Zelensky has so far ruled out relinquishing any land, but has proposed that Ukraine could redeploy its forces to an established line - but provided that Russia did the same.
Moscow currently controls about three-quarters of the Donetsk region, and some nearly all of the adjacent Luhansk region. The two regions form the Donbas industrial heartland.
It has been intensifying attacks against cities in Ukraine - particularly targeting power facilities. Russia has also made incremental advances in seizing additional Ukrainian land.
Ukrainian forces have retaliated at Russian targets with unmanned aerial vehicles, albeit with more limited success.
