Free, The distances in Europe are so close that there is only a few minutes from launch to detonation. Not enough time to communicate the hazard to a politician and get orders back. Anyway it is like the bully in the school yard with no one that will hit him back. BTW I read a article about China making the same anaisys regarding an attack on Taiwan. They figure as long as they don’t directly engage the US (no attacks on warships) that the US would not risk intervention fearing a nuclear war.
