Statements by the USA have until now sought to reassure the world of the unlikelihood of nuclear escalation.
However, in March 2023 when Russia announced that it was deploying tactical nuclear weapons in Belarus, NATO called the move "dangerous and irresponsible".
On Saturday, Biden echoed those words on the occasion of the first deployment, calling the deployment "absolutely irresponsible".
Strategically the moving of the warheads is significant as the first such transport since the collapse of the Soviet Union.
