The United States has been sending secret warnings to the Kremlin for months about the grave consequences of using nuclear weapons in Ukraine, it has emerged.

Washington has not spelled out to Moscow exactly what its response would be, maintaining a position of “strategic ambiguity”. The US has kept the warnings vague in the hope of inducing panic and uncertainty in the Kremlin.
