The United States government’s restrictions (or “ban”) on the admission of travelers from six Muslim-majority countries (which were chosen by former President Obama) — unless, as President Donald J. Trump has said, there can be vetting — triggered the anger of the Western academic community. Their distress seems to center around the exclusion from the United States of researchers and scholars from Islamic countries sanctioned by the American administration. Harvard, Yale and Stanford sued the White House. 171 scientific societies and academic organizations, protested what they wrongly titled Trump’s “Muslim ban”. “Among those affected by the Order are academics and students who are unable to participate in conferences and the free communication of ideas”, says an appeal signed by 6,000 scientists, academics and researchers around the world.
