In an extraordinarily blunt intervention, Air Chief Marshal Sir Richard Knighton warned that Russia’s military strength is increasing and is something to fear, with Russian troops now battle-hardened after spending the past nearly four years waging a full-scale war in Ukraine.


That’s also assuming the 75% never fire, and your anti-missile defense isn’t taking out ones that don’t work. Nuclear war isn’t a betting mans game. Everyone loses.
Ballistic missles are very hard to intercept at that. There’s no way there’s enough missile defense to even come close to stopping them all if Russia launched them all and even only 25% worked.
Same goes for anyone if the US launched them all.
Yeah and a large amount of those are MIRVs that release several shells per missile.
