The refusal to vaccinate foreign staff in the NHS recalls the refusal to vaccinate the workers who come into Israel every day from the West Bank. It suggests the belief that those are a separate species, and no more able than a dog or a duck to give Covid-19 to one's own.
There may be a degree of self-government in parts of the West Bank, but Israel is still the occupying power, with responsibilities under international law. Or are they saying that it is independent? But there may be a case for a British Nation-State Law after all. Just not the kind that Keir Starmer has in mind.
