Ukrainian President Volodymyr Zelenskiy and U.S. President Joe Biden stressed the importance of pursuing “diplomacy and deterrence in response to Russia’s military buildup on Ukraine’s borders,” according to a White House account of a telephone conversation on February 13.
Biden repeated his commitment to Ukraine’s sovereignty and territorial integrity and pledged to “respond swiftly” in the event of “further Russian aggression against Ukraine.”
Zelenskiy’s office reported that the Ukrainian president invited Biden to come to Kyiv “in the coming days.”
“I am convinced that your visit to Kyiv in the coming days…would be a powerful signal and help stabilize the situation,” the presidential office quoted Zelenskiy as saying.
The phone conversation came as Western powers continued to urge Russian President Vladimir Putin to de-escalate tensions, and several nations urged their citizens to leave Ukraine amid concerns that Moscow may be on the verge of military action against its neighbor.

Kyiv also called for a meeting of the Organization for Security and Cooperation in Europe (OSCE) within 48 hours for the purpose of discussing Russia’s buildup. Foreign Minister Dmytro Kuleba said Moscow had not responded after Kyiv on February 11 invoked a part of the OSCE Vienna Document to demand Moscow explain its activities.
“Consequently, we take the next step,” Kuleba posted on Twitter. “If Russia is serious when it talks about the indivisibility of security in the OSCE space, it must fulfill its commitment to military transparency in order to deescalate tensions and enhance security for all.”

U.S. Secretary of State Antony Blinken said on February 13 that the decision to evacuate most of the staff from the U.S. Embassy in Kyiv was justified by the threat of a Russian invasion, which he called "imminent enough," as several nations told their citizens to leave Ukraine amid Western warnings that Moscow may be on the verge of military action against its neighbor.

"Yesterday, we ordered the departure of most of the Americans still at the U.S. Embassy in Kyiv," Blinken said after talks in Honolulu with his Japanese and South Korean counterparts.
"The risk of Russian military action is high enough, and the threat is imminent enough, that this is the prudent thing to do," Blinken said, adding that a provocation could not be ruled out as an excuse for a Russian attack on Ukraine.
"No one should be surprised if Russia instigates a provocation or incident, which it then uses to justify military action it had planned all along," Blinken said.
U.S. national-security adviser Jake Sullivan said the same day that a Russian invasion of Ukraine could begin “any day now.”
“That includes this coming week before the end of the Olympics,” he added, referring to the Winter Olympics in Beijing, which are scheduled to end on February 20.
Sullivan added that the United States would continue making public its intelligence in an effort to block Moscow from staging a “false flag” operation that could be used as a justification for military action.

German Chancellor Olaf Scholz said the same day that NATO members and the European Union have already “carefully prepared” tough sanctions that “we can immediately put into force” in the event of an invasion.

The moves came as attempts by the leaders of the United States and France to convince Russian President Vladimir Putin to step back appeared to bear little fruit.
U.S. President Joe Biden told Putin in a phone call on February 12 that a Russian invasion of Ukraine "would produce widespread human suffering and diminish Russia’s standing" in the world, according to a White House statement issued after the call.
Biden also reiterated that the United States and its allies would "respond decisively" with "swift and severe costs on Russia" if Russia invades.

It remains unclear if Russia is willing to pursue a diplomatic path, the unnamed U.S. official said, adding that Russia may proceed with military action. Russia has consistently denied that it plans to invade its neighbor.
The Kremlin said Putin told Biden that the U.S. response to Russia's main security demands had not taken into account key concerns and that Moscow would respond soon.
Moscow is demanding guarantees from the West that NATO will not accept Ukraine and other former Soviet nations as members and that it will halt weapon deployments to Ukraine and roll back its forces from Eastern Europe.

British Defense Secretary Ben Wallace on February 13 warned against putting too much hope in talks, drawing a parallel between the Western diplomatic efforts and the European powers' policy of appeasement toward Nazi Germany ahead of World War II.
"It may be that [Putin] just switches off his tanks and we all go home, but there is a whiff of Munich in the air from some in the West," Wallace told the Sunday Times, referring to the 1938 agreement that allowed Adolf Hitler to annex part of Czechoslovakia as part of a failed attempt to persuade him to abandon territorial expansion.
"The worrying thing is that, despite the massive amount of increased diplomacy, that military buildup has continued," Wallace cautioned.
