White House warns Russia could invade Ukraine within days, urges

Any Americans still in Ukraine should leave “immediately,” the White House said Friday, as it warned that Russia could potentially launch an invasion of the country “any day now” — possibly even during the Olympics.

“Any American in Ukraine should leave as soon as possible, and in any event in the next 24 to 48 hours,” President Joe Biden’s national security advisor, Jake Sullivan, said during a press briefing.

Those remarks echoed Biden’s own warning Thursday for U.S. citizens in Ukraine to “leave now.”

“This is a very different situation, and things could go crazy quickly,” Biden said during an interview with NBC News’ Lester Holt.

On Saturday, Biden will hold a one-on-one call with Russia President Vladimir Putin, a White House official told CNBC.  French President Emmanuel Macron will also speak with Putin that day, CNBC has learned.

Sullivan noted that the U.S. is not certain that Putin has made a final decision to invade Ukraine. But “it may well happen soon,” he said.

On Friday, a senior Defense Department official told NBC News that Secretary Lloyd Austin has ordered another 3,000 American troops to deploy to Poland over the weekend.

They are expected to be in place by early next week, the official said. This latest tranche of troops will join the approximately 2,000 troops already deployed to Europe this month.

Russia has spent months building up its military presence at various points along the Ukrainian border. More than 100,000 Russian troops are currently stationed there.

Russia has now positioned about 80% of the forces required for a full-scale invasion of Ukraine, a western intelligence official and a U.S. official told NBC.

An invasion, if it occurs, was previously expected to come after the close of the Winter Olympics in Beijing in order to avoid a conflict with China, Russia’s ally.

The 2022 Winter Games, set to end on Feb. 20, have themselves been marred by controversy, including diplomatic boycotts over China’s human rights record and the recent revelation that a champion Russian figure skater failed a drug test.

But Sullivan on Friday stressed that an attack “could begin during the Olympics, despite a lot of speculation” that it would not.

Should Russia invade, the U.S. and its allies are “ready to respond decisively” through an array of actions, such as imposing “severe economic sanctions” and changes to NATO’s force posture, Sullivan said.

“If Russia proceeds, its long-term power and influence will be diminished, not enhanced, by an invasion,” Sullivan said.

“It will face a more determined transatlantic community. It will have to make more concessions to China. It will face massive pressure on its economy and…
