The rUK will not be asking for permission to keep Faslane, when they grant independence they will just retain Faslane. There are soverign bases in Cyprus so there is already a legal precedent Link
JY is that adult enough for you? 😉 Realistically iScotland would not be able to make the same demand of the rUK, iScotland just wouldn’t have the same clout as the country with the 6th largest economy on the planet, permanent seat on the UN security council, guaranteed EU member etc. iScotland need to appreciate the weak negotiating position they will have.
