So has France, but their nuclear weapons program is new.
I don’t think it’s weird to point out the little guys (especially former or current EU) getting strapped.
The first nuclear weapon tests for the UK and France were in 1952 and 1960, respectively. Nothing about that is new.

I think both the UK and France have had nuclear weapons programs since the 50s and 60s. Are you thinking about the "Northwood declaration" ? Where they both said they would coordinate their nuclear responses?
