President Joe Biden predicted Russia “will move in” to Ukraine, citing existential concerns by the country’s president, Vladimir Putin, even as he acknowledged disunity within NATO over how to respond to a “minor incursion”, writes CNN.

“It’s one thing if it’s a minor incursion and we end up having to fight about what to do and not do”, - Biden told reporters at an East Room news conference. “But if they actually do what they’re capable of doing with the forces amassed on the border, it is going to be a disaster for Russia if they further invade Ukraine”.

Later, asked to clarify what he meant by “minor incursion”, Biden said he drew the line at “Russian forces crossing the border, killing Ukrainian fighters”.

“I think that changes everything. But it depends on what he does, to what extent we"ll get total unity on the NATO front. It’s very important that we keep everyone in NATO on the same page. That’s what I’m spending a lot of time doing, and there are differences. There are differences in NATO as to what countries are willing to do, depending on what happens”, - said Biden.
