Russia’s deputy chairman of the Security Council, Dmitry Medvedev, on Thursday claimed that the recent discussion held between President Donald Trump and Russian President Vladimir Putin brought the world back from the "brink of the Apocalypse."

"It just so happened at some point that the U.S. appointed itself the country-in-chief on our planet with the exclusive right to wage a hybrid war against our people, to mete out justice and grant pardons. It was a grave mistake, which nearly wiped humanity off the face of the earth," he said, without mentioning that the West united behind Ukraine against Russia after Moscow launched the biggest invasion of a European nation since World War II.

"This is a lesson that must be learned by the arrogant American elites and the so-called deep state," he continued. "The quicker our adversaries realize this, the better.

"If they don’t… the Doomsday Clock will keep on ticking towards midnight," he added, threatening nuclear escalation. 

UKRAINE ADVOCATES TEAR INTO HEGSETH FOR GIVING RUSSIA ‘CONCESSIONS’ AT START OF PEACE TALKS: ‘BIGGEST GIFT'

Trump once again prompted geopolitical shock waves following his Wednesday call with Putin when he said in a Truth Social post that peace talks will start "immediately" – comments that came just hours after U.S. Defense Secretary Pete Hegseth said it was unrealistic that Ukraine would be allowed to join the NATO alliance. 

European leaders were quick to react with concern to comments from both Washington and Moscow, including EU foreign policy chief Kaja Kallas, who told Fox News Digital, "It's not wise to surrender Russia’s key demands before the negotiations even start."

"Any peace agreement requires the full involvement of both the Europeans and the Ukrainians to succeed," she continued. "Quick fixes are just dirty deals.

"Putin only responds to strength. Ukraine is resisting Russia’s invasion, and they have our full support. A bad deal for Ukraine is a bad deal for America and will embolden China," Kallas said. 

Kallas' comments came after she met with NATO defense ministers, who similarly came out in support of Ukraine and issued warnings to Washington. 

Lithuania Defense Minister Dovile Sakaliene said NATO leaders are facing "difficult discussions" with "two obvious choices."

"Whether we decide to fall under the illusion that Mr. Trump and Mr. Putin are going to find a solution for all of us – and that would be a deadly trap," she said. "Or we will, as Europe, embrace our own economic, financial and military capacity. And we will be the ones who will be deciding what will happen in Europe and in Ukraine with the United States."

In addition, Estonia Defense Minister Hanno Pevkur warned, "We have to understand that there will be no peace without Ukraine. 

"It cannot be so that someone will come and say when to talk. It has to be Ukraine," he added. 

Russian presidential spokesperson Dmitry Peskov on Thursday said Putin would be "pleased" to welcome international leaders, including Trump, to Moscow in May.

European leaders reacted with apparent concern to Trump’s and the Kremlin’s comments and said there can be no peace agreement without direct EU and Ukrainian involvement.

SOME CRITICS WORRIED TRUMP WOULD HAVE UKRAINE GIVE UP TOO MUCH FOR PEACE AGREEMENT WITH RUSSIA

Similarly, U.K. Prime Minister Keir Starmer said, "There can't be any negotiations about Ukraine without Ukraine being at the heart of it."

Seven European leaders from the U.K., France, Germany, Poland, Italy, Spain and the EU released a joint statement on Wednesday and insisted that they should be part of any negotiations on Ukraine's future. 

"Our shared objectives should be to put Ukraine in a position of strength," the statement said. "Ukraine and Europe must be part of any negotiations."

Ukrainian President Volodymyr Zelenskyy earlier this week said he would be willing to exchange the land Ukraine has seized in Russia for the land occupied by Moscow’s troops in its eastern regions. 

The Ukrainian president said he also spoke with Trump following his call with Putin on Wednesday about a "lasting, reliable peace."
