The latest assessments from U.S. and Ukrainian analysts say more than 100,000 Russian troops are deployed on the Ukrainian border.

But Putin also said he hoped diplomatic initiatives would proceed. The comments were his first public pronouncements since the New Year.

U.S. President Joe Biden said last week just such an invasion was “a distinct possibility” sometime in February. NATO and Washington have rejected Moscow’s demands outright but have offered further talks on issues such as disarmament pacts and establishing rules for staging military exercises.

The contents of replies from the United States and NATO were not disclosed. But Secretary of State Antony Blinken has said Washington had made clear its “core principles” and could not accept any notion of a Russian veto on NATO membership and on the choice of alliance partners to be made by Ukraine.
