adding they would need to build up their own nuclear capability, costing billions of euros
Billions of euros is not a big sum for nuclear weapons. If others ask politely, maybe France or the UK will give a few tips about making them cheaper.

Heyva Sor is real and if you can, I am sure they welcome any help. :)
