The petition against Donald Trump’s ‘state visit’ to the United Kingdom has gathered over 1.8 million signatories. (I am one of them). Of particular concern to many of these signatories has been Trump’s ‘Muslim ban’, and its perceived infringement of international human rights law. But there is a curiosity, one that has been seized upon by those more positively disposed to Trump. Trump’s actions to date are surely less objectionable, from a human rights perspective, than the historical actions of Saudi Arabia and China, and the leaders of both of those countries have enjoyed recent state visits to the United Kingdom with (relative to Trump) little outcry. Can these differing scales of public reaction be justified? I suspect not; only explained.
