Top Biden aide warns Russia’s Ukraine invasion could come ‘any day’
- ‘If war breaks out, it will come at an enormous human cost to Ukraine, but … it will come at a strategic cost to Russia as well,’ said US national security adviser Jake Sullivan
- The US government has stepped up warnings in recent days that Russia increasingly seems intent on further invading Ukrainian territory

White House national security adviser Jake Sullivan said on Sunday that Russia could invade Ukraine “any day,” launching a conflict that would come at an “enormous human cost.”
“If war breaks out, it will come at an enormous human cost to Ukraine, but we believe that based on our preparations and our response, it will come at a strategic cost to Russia as well,” Sullivan said.

Sullivan did not directly address reports that the White House has briefed lawmakers that a full Russian invasion could lead to the quick capture of Kyiv and potentially result in as many as 50,000 casualties as he made appearances on a trio of Sunday talk shows.
Among those military indicators: An exercise of Russia’s strategic nuclear forces that usually is held each fall was rescheduled for mid-February to March. That coincides with what US officials see as the most likely window for invasion.
