The Washington Post quoted US and European officials as believing that the Russian invasion may occur as early as next week.
The newspaper reported that a quick meeting was held in the White House Situation Room, Thursday evening, to discuss new intelligence about the possible Russian attack.
She explained, quoting a source who declined to be identified, that Russia is “already planning to portray a mock attack against Russian territory to justify its invasion of Ukraine.”
The source said: “Moscow is trying hard to create a justification for war or justification for the invasion.”
National Security Adviser Jake Sullivan hinted to reporters that Russia might carry out a “false flag” or “deceptive flag” operation to blame the Ukrainians before attacking them.
And “false flag” means secret operations that use camouflage, so that it appears as if a group planned and carried out these operations other than the real group.
“If Russia chooses to do this, it must be held accountable,” Sullivan added.
