>> Regarding the Stinger Missile Defense System the US provided Ukraine https://en.wikipedia.org/wiki/FIM-92_Stinger, it is capable of carrying nuclear warheads that could hit Moscow in single digit minutes from the Ukrainian border.
I see from your link that Stinger is a light shoulder-fired weapon that has a warhead of 3 kg and range of 8 km. How should that carry a nuclear warhead to Moscow?
It doesn't. I was mistaken. Apologies, I'm not an expert on arms capabilities and I mixed up my arms in haste.
Ukraine does now have French SCALP cruise missiles that are nuclear capable, with a stated range of 160 miles (250kms) - not enough to decapitate Moscow, but close enough to be pretty threatening. [0]
