Reasons for the comparative quiet on Arab campuses and streets may range from a fear of angering autocratic governments to political differences with Hamas and its Iranian backers or doubts that any protests could impact state policy.
American students at elite universities may face arrest or expulsion from their schools, but harsher consequences could await Arab citizens protesting without state authorisation.
And U.S. students may feel more motivation to protest as their own government backs and arms Israel, while even those Arab countries that have full diplomatic relations with it have been strongly critical of its military campaign.
