It would have convinced me that their arsenal was ready to be employed on short notice. Had Putin detonated a small nuke on the tip of a missile and a large nuke I would not harbor the suspicions that the corruption throughout the Putin government that siphoned off billions of rubles meant for maintenance and periodic component testing of the nuclear arsenal into the pockets of corrupt bureaucrats, Generals, and Colonels. It would also have scared off smaller countries from sending F-16s and MBTs to Ukraine for fear of being moved up on a list of retaliatory targets.GAC06 said:
How would that have changed anything? We know Russia has nukes.
The cost of a couple of warheads from the hundreds that Russia had at the end of the Cold War would be very small compared to the signal that it would send. As pointed out today, the ICBM launched at Dnipro was a waste of money in terms of the damage that it inflicted but it sent a message.
