Ukrainian President Volodymyr Zelensky says European allies have not given him solid assurances that they will protect his country in the case of a future Russian attack.
"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 stated to the press on midweek.
These remarks follow a day after the UK and France inked a declaration of intent on deploying troops in Ukraine if a peace deal to conclude the conflict with Moscow is finalized.
However, comprehensive defense assurances have not been agreed. The US, which has been spearheading initiatives to end the invasion, reportedly did not sign such a pledge at talks in Paris on the previous day.
After the Paris talks, which involved some 30 countries that comprise the group termed the 'Coalition of the Willing', UK Prime Minister Sir Keir Starmer said the UK and France would "establish military hubs across Ukraine" to prevent any future incursion, while French President Emmanuel Macron subsequently indicated a significant number of soldiers may be deployed.
Allies proposed that the US would assume a leading role in monitoring a truce. But the key issue of ceding land that Ukraine is being asked to grant to Russia as a component of the settlement terms are still being discussed.
Moscow has thus far remained silent on the announcement made in the city of Paris.
Russian President Vladimir Putin initiated a comprehensive military assault of Ukraine in the early months of 2022, and Moscow now occupies about 20% of Ukraine's land.
The UK Prime Minister characterized the joint statement as "a vital part of our commitment to stand with Ukraine for the foreseeable future".
He continued: "It establishes the pathway for the legal framework under which allied military personnel could function on Ukrainian soil, securing Ukraine's skies and seas, and rebuilding Ukraine's military for the future."
The Ukrainian leader praised that agreement as a "significant leap of progress".
Twenty-four hours afterward, however, he appeared less optimistic.
"I perceive the determination, the political will, and that the allies are prepared, and the partners are ready to give us strong sanctions, powerful defense assurances," he said when asked if European countries would come to Ukraine's aid.
"But as long as we don't have such security guarantees - legally binding, supported by parliaments, backed by the U.S. Congress - this crucial issue remains unresolved. And should they materialize, you must ultimately depend first and foremost on your own strength."
Negotiations in Paris were also significant due to the attendance of envoys from former President Trump's administration, Steve Witkoff and Jared Kushner.
One envoy stated the participating countries "mostly completed" their work on finalizing security arrangements.
Last week, the President indicated a peace deal was "90% ready".
Territorial concessions and security guarantees have been at the forefront of unresolved issues for diplomats.
Putin has repeatedly warned that Ukraine's military must pull back from the entirety of the Donbas region or Moscow will take control, rejecting any compromise over how to end the war.
Zelensky has so far ruled out relinquishing any land, but has proposed that Ukraine could withdraw its troops to an agreed point - but provided that Russia reciprocated the action.
Moscow currently controls about three-quarters of the Donetsk region, and some 99% of the adjacent Luhansk region. The two regions constitute the Donbas industrial heartland.
It has been intensifying attacks against Ukrainian cities - with a focus on power facilities. Russia has also made incremental advances in capturing more Ukrainian territory.
Ukraine has hit back at objectives inside Russia with unmanned aerial vehicles, albeit with varying degrees of effectiveness.
