Julia Ioffe, a senior editor at “The New Republic,” tells us whether she thinks the U.S., Russia, Ukraine and EU deal can hold. Then, film contributor Milos Stehlik reviews Jim Jarmusch’s film “Only Lovers Left Alive,” and Nari Safavi gives us his weekend picks: a documentary examining big oil in Africa, a lecture on the role of the internet in the Muslim world and an Easter Smorgasbord.
