Its publications also show that Western intelligence agencies believe Putin is not interested in compromise. The memorandum will what Putin has been saying - the "root cause" of the war is NATO's eastern expansion in Ukraine and fierce Nazism.

Putin spokesman Dmitry Peskov told reporters on Tuesday that the memorandum "is aimed at getting rid of the root causes of this conflict." "It is wrong to expect some immediate decisions and breakthroughs here," he said, adding that Ukraine's "we are waiting for a reaction to the memo".

Ukraine and its Western supporters say Russia's claims about Nazism are ridiculous, especially when the country is governed by the Jewish Zelenskyy. NATO and its supporters argue that the alliance will only grow because the former Soviet republics (such as Latvia, Lithuania and Estonia) have voted to get protection from Russia.

Not only does Ukraine not very accept Russian absolutist terms, but scholars previously interviewed by NBC News think Russia knows they won't. Many view peace talks as a charm that both sides know will fail, just to avoid President Donald Trump’s anger and impatientness.

Former Russian President Dmitry Medvedev - always hawkish voice - unabashed in the luxurious Ottoman era Çırağan palace of how he viewed these discussions.

Medvedev now wrote in the vice chairman of the Russian Security Council: “Under the unrealistic conditions that others invented, negotiations in Istanbul are not required.” Instead, the purpose of his statement was “a quick victory and a complete destruction of the neo-Nazi government.” The goal, he said, is “the focus of the Russian memorandum published yesterday.”

Russia, unlike Ukraine, has been different from Ukraine's attacks on military targets, and has continued to bomb Ukrainian civilians. Zelenskyy said it "brutally attacked" the embattled city of Sumi on Tuesday, killing at least three people and injuring "many people."

Both sides remain completely opposed, and Trump's next move may be key.

Once promised to end the war within 24 hours, he was so frustrated by the stubborn reality that he threatened to walk away.

Hope there is another Russian-American prisoner exchange, and even hope for a meeting between the two presidents. When the memo inevitably encounters Trump’s desk, when he was asked about this during a Q&A session in the Oval Office, the president can react in several different ways, said Nixey, a London Russian expert.

"He would either say, 'Yes, but look at what the Ukrainians did to Russia, so this memorandum is not surprising," Nixy said. "Or he would say, 'Putin didn't play. The facts aren't like I thought. I'm going to wash the whole thing."
