My Dad was SIOP cleared and involved in nuclear war planning. He always used to say, “A lot of things have to go right for an ICBM warhead to detonate on target, and a lot of things can go wrong.” Just ask Elon Musk.
Their current ICBM force went into service in 1988. They’ve been sitting around in Siberia for decades, during periods of extremely low military funding, amidst the rampant corruption of the Russian state. We can hope that many will malfunction. We can’t rely on it. And even one hitting target will be an utter horror show.
No real enemy would target Washington DC. It would end the confusion.
