Kruschev resisted similar temptations. Since 1945, all the presidents and chairmen have resisted all the generals who thought nuclear death a useful option. That's not the only change in our attitude toward war since 1945. Vietnam was responsible for that. That is because Vietnam was our least censored and most visually accessible war.
People forget how heavily censored World War II was.
No pictures of dead American soldiers were released to the press until late 1943, and even then few American newspapers printed many of them. The Office of War Information vetted Hollywood movie scripts and newsreels to be sure they presented the right attitudes, and Hollywood happily complied, even after the war was over. The military adored that movie. It was the only movie we got to see when I was in Marine Corps boot camp in 1953. They showed it to us twice.
