> Defensive systems can’t work and are inherently destabilizing even though everyone knows they can’t work.
All of those clauses are immensely important for everyone to understand.
First, "can't work"; because the math simply does not math, so to say.
Second, "inherently destabilizing"; among other reasons, if you think your imaginary "iron/golden dome" will protect you, you do all kinds of insane and reckless things that could quite literally at best be civilizational collapse, or even human life ending.
Third; "everyone knows they can't work" is not something I am at all convinced of, or at the very least those who should and really need to know that, don't actually know it, because "DC" is a self-licking ice cream cone that huffs its own farts to the point that the system reinforces those characteristics by selecting for them. The result is that the whole narcissistic system believes its own decadent nonsense.
