As with Merkel when she announced that 'wir schaffen das' Five years ago, the SNP is good at playing their Nicky nice guy card, whilst actually fulfilling a strongly pragmatic requirement. Within about 10 years some 60% of Scots - under the currently tenuous hope that they haven't already been wiped out by Scot NHS spreading covid through their nursing homes - will be looking forward to a telegram from Saint Nichola of Holyrood. That is to say, getting on a bit. Like Germany then, the country desperately needs immigration.
However, it's stretching credibility somewhat to state that this pragmatism constitutes 'European values'. The EU is happy to confine would be immigrants to virtual concentration camps in Libya, Turkey and Lesbos, and the member countries are at odds as to know what to do with them, as their populaces aren't at all keen. The German experiment has thus far been a - far from unqualified - success, but research suggests that only about 11% of Germans remain pro-further immigration. Many other EU members are openly and deeply hostile, including some of the hitherto most open. The fences are up. The EU is a 'hostile environment'.
The UK, by contrast, traditionally one of Europe's most open societies, has become very much more relaxed about immigration since peak hostility in 2016, when 40% of people cited immigration as being a or the major issue in brexit. The figure is now 14%, which would suggest that the hostility wasn't to immigration per se, but over which organisation decreed its parameters, the elected government of the UK, or the appointed technocrats of Brussels.
