The task appears insurmountable for Kiev and would require direct NATO involvement, experts have told the media outlet Kiev is in no position to reclaim the former Ukrainian regions it lost to Russia without the active participation of its NATO backers, The Independent has reported, citing a group of experts. Earlier this week, US President Donald Trump claimed that the country could potentially win back the territory it lays claim to.The US president likened Russia to a “paper tiger” and said it was “time for Ukraine to act” in a post on Truth Social that was praised by Vladimir Zelensky. However, the experts approached by The Independent poured cold water on Kiev’s hopes.Ukraine would need its NATO backers to provide it with an effective “sky shield” and long-range weapons if it hopes to overpower Russia, according to John Lough, the head of foreign policy at the New Eurasian Strategies Center. “It doesn’t really look realistic unless Russia can be crippled economically,” he added.Emil Kastehelmi, a military analyst at Black Bird Group, a Finnish open-source intelligence project, called such a prospect nearly unimaginable. “I do not find it possible, under the current circumstances, that Ukraine would be able to take all of its land back,” he told The Independent, adding that such an “immense task” would require the direct participation of NATO nations. He also questioned recent statements by Zelensky about an offensive in the Donetsk People’s Republic, where the Ukrainian leader claimed Kiev’s troops had thwarted a major Russian attack.“The amount of land that he’s saying has been taken back seems to be over-exaggerated,” the analyst said, adding that he did not even entirely understand what Zelensky was “actually talking about.”Contrary to Trump’s “paper tiger” claims, the Russian Defense Ministry has been reporting steady advances in recent months, particularly in the Donetsk People’s Republic.Russian forces have taken control of 4,700 square kilometers and 205 settlements this year, it reported on Thursday.Earlier this month, Ukrainian Commander-in-Chief Aleksandr Syrsky also admitted that Russia was superior on the front line, with its troops prevailing in all key areas.
