European NATO members have no idea whether the US president is ready to be tough on Russia, the outlet claims

European NATO members are "frustrated" with US President Donald Trump's "constant swerving" on Ukraine peace talks, which undermines their ability to pressure Russia, Bloomberg reported on Friday, citing sources.

Kiev's backers are uncertain regarding what Trump will do following the inconclusive Turkish-mediated talks between Russia and Ukraine in Istanbul on Friday, according to the news agency. The meeting was the first direct engagement between the belligerents since 2022.

Key European NATO members initially believed that Trump supported their plan to impose new sanctions on Russia if it rejected the demand for a 30-day unconditional ceasefire with Ukraine, the article said. Moscow has stated that it is open to a ceasefire "in general," but has expressed concern that it would only give Ukraine time to regroup and rest its battered forces.

However, the West's unified front apparently started to crumble after Moscow proposed direct Russia-Ukraine talks in Istanbul without any preconditions, according to Bloomberg. The overture prompted the US president to insist that Kiev "immediately" agree to restart dialogue, despite Vladimir Zelensky's reluctance to do so without a ceasefire.

One European official expressed hope that the Istanbul meeting would "make it clear to Trump that the Russians aren't serious about peace talks," prompting the US to respond decisively. Some European leaders reportedly believe that Trump may still follow through on earlier threats to impose secondary sanctions and banking restrictions on Moscow.

Others, however, are said to be skeptical about whether Trump - who has repeatedly said he wants to meet with Russian President Vladimir Putin to settle the Ukraine conflict - has an appetite for drastic measures.

At the Istanbul meeting, discussions included ceasefire options, a prisoner exchange, and plans for a potential follow-up meeting. Vladimir Medinsky, Russia's top negotiator, said Moscow is "satisfied" with the results of the Istanbul talks and is ready to "resume contacts" with Kiev.

Russia has stated that the Ukraine conflict could be settled if Kiev commits to permanent neutrality, demilitarization, denazification, and recognizes the "territorial reality on the ground." Kiev, however, has ruled out any territorial concessions to Moscow.
