Quite recently there was a NATO war game A small drone team from Ukraine played the invader. The small team crushed the larger conventionally armed NATO force.
Now, however much we may laugh at Russia's claim ro be the second-best military in the world, they definitely are the second-best drone army. NATO needs Ukraine if they don’t have the USA. Perhaps they will need Ukraine even if the USA fulfills their treaty obligation. In any case, the real purpose of NATO isn’t defeating an invasion of a member country; it is being strong enough that it would so clearly defeat an invasion that nobody would invade.
What any European NATO country could do:
Build a drone plant with Ukraine providing the design team, and the NATO country providing the production machinery. The output would, at first, go all — or almost all — to Ukraine. When the NATO country so request, 90% of the production would flow to the NATU country for a period up to as long as the first production flowed to Ukraine. Ukraine would also provide instructors. (Drones used in 2024 would be little use in 2026. Similarly, we may assume that drones produced in 2026 will be of little use in 2028. By providing output now to the country that needs them now, we’ll apy Ukraine what it wants. By providing output in a future uncertain date to a country which might need them then, we’ll give the NATO country what it needs. If the NATO vountry never needs the, it will have been provided with peace.)
