  • The reality is that “tactical” and “strategic” are functionally meaningless adjectives when applied to weapons or systems.

    Theoretically, “tactical” refers to how a military unit engages another military unit. It is how a commander wins a battle against an enemy unit.

    “Strategic” refers to how a nation engages another nation. It is how a government wins a war.

    The term “tactical nuke” referred to something that a lower level commander could have been authorized to use under his own judgment. If Soviet tanks were rolling across Europe during the cold war, commanders may have been granted the discretion to use small nuclear weapons to halt their advance.

    Since the the doctrine of Mutually Assured Destruction was established, there has been no such thing as a “tactical” nuke. Any wartime use of a nuclear weapon of any kind demands an escalation to total annihilation. I used the term “tactical” ironically, to refer to a pre-“MAD” doctrine that can no longer exist.

    In declaring that conventional bombs cannot penetrate this fixed bunker, it seems that someone is pushing for unconventional warfare. The reality is that this bunker is not impenetrable. It shares the same weakness as any bunker: getting into and out of it. Bomb the entrances to the bunker, and it will take months or years to tunnel back in. Whatever they are doing inside it, they won’t be doing until they manage to dig it up again.

    You seal everything but the battery in one watertight compartment. The battery is a sealed, self-contained package, in a second compartment. Dunk the phone, the only thing that gets wet are the battery contacts, which are protected the same way that earbuds with magnetic chargers are protected: if the contacts get wet, the battery shuts itself off until it has been dried off.


  • If a die is weighted, the first roll is no longer 1/6 probability to get a 7

    Yes, actually, it is. No matter what the first die lands on, there is a 1 in 6 chance that the second die will land on the corresponding value necessary for a “7”. You could glue the first die to the table with “6” (or any other number) showing, and there will be a 1 in 6 chance that the second die will bring the sum to 7.

    Weighting one die (to favor “6”) will increase the probability of every outcome over 7, and will decrease the probability of every outcome under 7, but the probability of rolling a 7 will not change.
