"the potential of MAD (Mutually Assured Destruction) all but guarantees that nuclear countries will never attack each other for fear of nuclear escalation."
I would feel a lot more secure in the efficacy of MAD if war was rational in the first place. History shows it is anything but.
It hasn't even been 100 years since the last nuclear weapon was used offensively, but already the world has come dangerously close to starting a nuclear war.
Numerous accidents involving nuclear weapons have happened. Critical and very dangerous errors were made in detecting that nuclear war had already begun when it hadn't. Countries with nuclear weapons have come close to going to war with each other (India and Pakistan, Cuban Missile Crisis). Weapon-grade nuclear material and nuclear weapons have gone missing. The American nuclear weapon launch codes were all 0's for something like 20 years.
It is an open question how a nuclear power will react to having a nuclear weapon exploded on their soil (potentially by terrorists under a false-flag operation) but it likely won't be a calm and measured response against the perceived perpetrator. If this happens in a poweder-keg like the Middle East, the ensuing chaos could easily draw in other nuclear powers.
Crumbling nuclear-weapons and launch-detection infrastructure in the former Soviet republics is still a major concern because of continued and increasing potential for accidental launches of weapons still aimed at their former Cold War foes, not to mention the renewed possibility of a second Cold War that has been in the news recently, and Putin's overt threats of the use of nuclear weapons.
You are absolutely right to be skeptical about MAD, the invention of genius civilians like Robert Strange McNamara who also brought up the horribly fought Vietnam War, the previous generation F-35, the M16/M4, etc. etc. etc.
The Soviets never bought into it, and rightly judged us to be utterly evil to target their children in their homes instead of military targets like we'd done prior the the early '60s.
As you implicitly note, we can be sure nuclear weapons will again be used in anger. Although the dangers from a false flag operation are potentially less than you think, in that each weapon has a radioisotope signature which tells you everything from its design to where the fissionable materials came from. So we'd know who manufactured it, or so I gather and believe from my study of all this (born when Eisenhower was still president, I'm a child of the cold war with e.g. my mother's Civil Defense Block Mother sign a dozen feet from me).
I don't think its right to judge the rationality of decisions based on their outcome. The question is whether war was a rational decision at the time. From a realist perspective anything decision is rational if it can lead to an improvement in the chances for survival. If war leads to a relative increase in my power even if I may lose soldiers and resources, then its worth it.
If country A has 100 soldiers while country B has 20 soldiers, even if the cost of war is a 2 to 1 loss in soldiers, war would result in the absolute power of country A.
In a conflict between two countries with nuclear weaponry, the core logic is the same, but the paradigm is different. Nuclear warfare can erase both countries off the face of the earth. This follows from the fact that to combat nuclear attacks, countries started adopting hair-string triggers to destroy the adversary before they can send more warheads their way... except now every country is doing the same thing. In this case, forget the relative nonsense, anyway you cut it, nuclear warfare is not rational for countries because it will end their survival.
My belief is that MAD is sound. And my underlying assumption is that countries tend to think rationally when dealing with international relations. Regardless of leadership, countries do whats best for them an overwhelming majority of the time. Case in point, how often has the U.S. (the bastion of freedom) voluntarily helped countries/people when the U.S.' interests were not directly involved? Also, observe how a seemingly crazy country like North Korea plays the game shrewdly by varying is strategy depending on its adversary.
I agree that there is a threat that nuclear weapons will get in the wrong hands and, in that case, I think its more than probable that disaster would ensue. But the safety and standards for handling infrastructure degradation has improved significantly since the early days of nuclear weapons (when many were lost to the ocean and never recovered) . As for Putin's threats, its nothing a good back and forth of denouncing and condemning can't fix.
