Change Square has changed, but not for the better. The tent city outside Sana’a University that was the focal point of year-long protests against Yemen’s President Ali Abdullah Saleh did not fold up after the dictator was finally ousted at the end of February. On the contrary, many of the tents have taken on a sense of permanence, with plastic and canvas giving way to cinder-block walls. Where youthful revolutionaries chanted anti-Saleh slogans and braved assaults by the dictator’s troops and thugs, vendors now flog shoes, toys and replica soccer jerseys. A hard core of protesters remain, but with an elected President — Abd Rabbuh Mansour al-Hadi — now running this impoverished nation, their protestations, for the most part, get little attention.
