I do understand the significance of your view that the US will sell us (Europe) equipment to sell on to Ukraine; however I would have thought that can only go so far (cost and time wise) and probably only if Germany, who has now given itself permission to rearm, pays for most of it.
My main point was that the US, in the not too distant future, and in one way or another, is going to pivot away from involvement in and providing immediate support for Europe and focus on the South China Sea.
France has its own independent nuclear armaments, Germany will also (no doubt) go down that route, we are likely to be the only ones left in hock to the US on nuclear defence issues. Fending off an emboldened Russia (if it is successful in neutering Ukraine) which will then no doubt eye the Baltic States as the next domino that Putin will seek to 'tumble', and it will in essence require a return to the cold war 'mutual annihilation' standoff; as I doubt anyone will be stupid enough to try to put 'boots on the ground' in Russia.
Thereafter, and with some sort of European 'umbrella nuclear cover' being promised by a combined France, Germany and UK 'pact', it might be capable of holding the ring; but will nevertheless not stop ever country who can arm itself with nuclear capability, attempting to do so, and all others will strive to do so, or offer themselves for annexation to a 'nuclear state'.
Once the control/restraint on nuclear deployment in the West is released by the US, the world indeed will become a very dangerous place.
