I think you've explained MAD in much better terms than most people I've heard.
But I think that while you and me completely agree on why MAD worked, we both disagree on whether or not it would continue to work in a war.
I came to my conclusions after considering that Hitler had direct control over thousands of gas munitions ready to fire in the final days of the Reich, but didn't order their launch. And he was crazy as a loon.
Also, the Soviet Union (after Stalin) was led by sane individuals who knew that for the most part, they probably weren't going to get out of a war with the West with their skins intact.
On a more concrete level, if war came, their vacation dachas were probably going to be kindling. And their chauffered limousines would be of little use without the gasoline to drive them.
Tom Clancy said once in an interview about Red Storm Rising that people always walked up to him and remarked that the least believable part of the book was the beginning. He replied that that was because he could never come up with a logical reason for NATO and the Warsaw Pact to go to war.
I happen to agree with that thought.
But that's alright, you're entitled to your opinions. It's not the kind of thing I'm probably going to change. And to be honest, you defended yours pretty well.
And I totally agree with you: the Aleutians are peripheral. But that's part of why the thought of a front there in a hypothetical "Third World War" is so interesting.
To boil it down, I can go to my used bookstore, close my eyes in front of the military fiction rack, and grab a book that is probably about US forces in Europe or the Middle East at some point in time for some reason or other. This has a distinct air of originality to it. Especially because I spent a few summers in Hyder, Alaska.
Ultimately, war is one of those topics that is interesting to discuss and terrible to live. I am glad that both the Soviet Union and the United States essentially followed my point of view that a shooting war would risk MAD on the spot and never tried it.
Mac, I'll give you a prediction. India and Pakistan will never go to a full scale war again. I know it sounds optimistic, but I really think that's where the line is. Because a full scale war is going to, at best, risk MAD.
If you are right, then Pakistan and India will go for a full scale war and neither side will press the buttons. I hope you aren't. I'm pretty sure that half the point of deterrence is stopping a conventional war because Risking MAD is not worth the gains of a conventional war.
Does MAD break down in a shooting war? I think MAD is even stronger in a shooting war than without one, and that if a "incident" occurred the offending party would quickly pull out because the game is up--the nukes are on the table.
Somehow, you are missing this part on the list of Events:
Soviet Union Attacks Alaska
USA Threatens Nuclear Destruction.
Soviets either pull out or the nukes fly.
The United States has no real intention of fighting this war, they didn't start it and they certainly don't trust the Soviet Union to be sane. So they make the nuclear threat on day three, and press the buttons on day seven. Are the Soviets going to launch first? If they are insane enough to attack the United States without provocation, I think the USA has to launch.
Yes, this is terrible. This is a world in ruins, a world that totally trashed itself--and I don't deny that this is the worst case scenario. But consider that MAD is an explicit threat--fight a war, lose just about everything. The United States doesn't want to press the buttons, but given the Soviet Union's madness, they are pretty sure that the Soviets will press them.
And so, while the Soviet Union has decided to reduce the world from its former state to a pile of molten slag, the United States has decided to act so that its postwar population is around fifteen million instead of five million.
One would probably want to know what the last thoughts of the Politburo will be in its bunker deep beneath Moscow. Shock, confusion, perhaps guilt and remorse for essentially starting a nuclear war. What had they hoped to gain-West Germany? The Aleutian Islands? Well, they had damned their people to either death or misery for a century. As the sirens wail, they will at least understand why their predecessors, including Stalin himself, did not attack the West.
MAD means that the war is either an incident that is quickly solved or it is a glassing. A long war will not happen without a casus belli and a very VERY narrow focus. WW3, started by a Soviet Attack, ends one week later in a nuclear exchange. That sounds like a terrible story but also the real reason why no one actually had a third world war.
