Not objectionable , but any nuclear use by any side in this day and age , will bring down global wrath . It’s considered too bad , too uncivilized , too inhumane , etc ………….its the big no no . Putin is not an idiot , he knows this , and even on a small scale , any nuclear weapon used by any side , starts a chain reaction with all nuclear capable countries , they have to go on alert , and thats when things have a good possibility of getting out of control fast . Thats why nothing happened between the US and Soviet Union , too risky for either side , and why all sides go to great pains to keep things conventional . If dropping a nuke , even a small one , was that simple , we could have used that in Iraq and Afghanistan , and not had to be there for years on end . Just Sayin .
