You opened a Pandora box. I think are all valid points and all are in my opinion under discussion. Especially nuclear deterrence. Both UK and France in their doctrines consider the use of nuclear weapon to defend allies. But we probably need more capabilities especially for air launch.
However, I would like to stress that some of the point I raised have priority. After also satellites 🛰️ is an area where we should grow and in this Europe economy could benefit. If we have to spend in defence, we should maximise what we spend in Europe. Our security our investments our growth.
