Russian President Vladimir Putin warned Wednesday that Moscow will seek to extend its gains in Ukraine if Kyiv and its Western allies reject the Kremlin`s demands in peace talks.

President Donald Trump has unleashed an extensive diplomatic push to end nearly four years of fighting following Russia`s full-scale invasion of Ukraine in February 2022, but Washington`s efforts have run into sharply conflicting demands by Moscow and Kyiv.

Speaking at an annual meeting with top military officers, Putin said Moscow would prefer to achieve its goals and "eliminate the root causes of the conflict" by diplomatic means, but he added that "if the opposing side and its foreign patrons refuse to engage in substantive dialogue, Russia will achieve the liberation of its historical lands by military means."

He also referred to European leaders as pigs, or swine.

"Everyone thought that in a short amount of time they could destroy Russia," Putin said. "And the European swine immediately joined the work of the previous American administration in the hope of profiting from the collapse of our country."

He said that while the Trump administration had demonstrated readiness for a peaceful resolution, "it is unlikely that this will be possible with the current political elites" in Europe.

Ukraine and its Western allies regards Russia`s actions as a violation of its sovereignty and an unprovoked act of aggression.

Putin claimed that "the Russian army has seized and is firmly holding strategic initiative all along the front line" and warned that Moscow will move to expand a "buffer security zone" alongside the Russian border.

"Our troops are different now, they are battle-hardened and there is no other such army in the world now," he said.

Putin praised Russia`s growing military might and particularly noted the modernization of its atomic arsenal, including the new nuclear-capable intermediate range Oreshnik ballistic missile that he said will officially enter combat duty this month. Russia first tested a conventionally armed version of the Oreshnik to strike a Ukrainian factory in November 2024, and Putin has boasted that it`s impossible to intercept.

His tough statements follow several rounds of talks this week between Ukrainian, American and European officials on a U.S.-drafted peace plan.

Ukrainian President Volodymyr Zelenskyy said after meeting with U.S. envoys in Berlin that the document could be finalized within days, after which U.S. envoys will present it to the Kremlin.

Putin wants all the areas in four key regions captured by his forces, as well as Crimea, which was illegally annexed in 2014, to be recognized as Russian territory. He also has demanded that Ukraine withdraw from some areas in eastern Ukraine that Moscow`s forces have not captured yet.

The Kremlin also insists that Ukraine abandon its bid to join NATO and warns it won`t accept the deployment of any troops from NATO members and will view them as "legitimate target."

Zelenskyy has expressed readiness to drop Ukraine`s bid to join NATO if the U.S. and other Western nations give Kyiv security guarantees similar to those offered to NATO members. But Ukraine`s preference remains NATO membership as the best security guarantee to prevent further Russian aggression.

At the same time, Zelenskyy has rejected Moscow`s demands that it pull back its troops from other areas that Russia has not been able to take by force.

The Ukrainian leader described the draft peace plan discussed with the U.S. during talks in Berlin on Monday as "not perfect" but "very workable," noting that Kyiv and its allies were very close to a deal on "strong security guarantees." But he also emphasized that the key issue of control over territory remain unresolved.
