It was a big weekend for Israel conferences. In Washington, the American Israel Public Affairs Committee (AIPAC) held its annual policy conference. At Harvard’s Kennedy School of Government, a 27-year-old student from the Gaza Strip named Ahmed Moor organized a conference on the “one-state solution”: the idea that the Jewish state of Israel should be replaced with one ostensibly secular, binational state encompassing Israel, the West Bank, and the Gaza Strip.
