Ah, thought I already did. On the BBC, confirming the Danish approach:
“The issue about visiting warships, etc., no country ever confirms the existence of nuclear weapons on its warships – that is well known. This is an issue all non-nuclear countries have to face up to within NATO and out of NATO and we will do exactly the same thing.”
Personally I think it's a splitter's option, really not a fan- it's basically don't ask/don't tell, which is hypocritical- though pragmatic. We should be going conventional only, like Spain... And to be fair that would be the SNP's choice, if they get to make it, but it's good to have alternatives in place.
The reality is, NATO doesn't need its new members to be nuclear- the existing nuclear powers guard their arsenal pretty jealously, naval deterrants are designed for long patrols and by definition avoid spending time tied up outside of home ports, land-based weapons don't travel in this way, air-based we're not needed. But we've got more to offer to NATO than plenty of other members- a strategically useful location, existing early warning infrastructure etc, and would still have more of a military force than Iceland, Albania etc (and Albania are one of the most recent additions)
