Russia could invade Ukraine at any time and might create a surprise plea for an attack, the United States said on Sunday, as it reaffirmed a pledge to defend “every inch” of NATO territory.
Russia has more than 100,000 troops massed near Ukraine, which is not part of the Atlantic military alliance, and Washington – while keeping open the diplomatic channels that have so far failed to ease the crisis – has repeatedly said an invasion is imminent.
Moscow denies any such plans and has accused the West of “hysteria”.
German Chancellor Olaf Scholz, on the eve of a trip that takes him to Kyiv on Monday and Moscow for talks with President Vladimir Putin on Tuesday, called for Russia to de-escalate and warned of sanctions if Moscow did invade.
A German official said Berlin did not expect “concrete results” but diplomacy was important.
In Washington, President Joe Biden’s National Security Adviser Jake Sullivan said an invasion could begin “any day now”.
“We cannot perfectly predict the day, but we have now been saying for some time that we are in the window,” Sullivan told to media.
U.S. officials said they could not confirm reports that U.S. intelligence indicated Russia planned to invade on Wednesday.
Sullivan said Washington would continue sharing what it learned with the world in order to deny Moscow the chance to stage a surprise “false flag” operation that could be a pretext for an attack.
It would also “defend every inch of NATO territory and Russia we think fully understands that message,” Sullivan added in a separate CBS interview.
