Our government’s concerns that the opening of the Rafah crossing by Egypt will increase the chances of arms smuggling into Gaza are legitimate. Its fears of terrorists exploiting the crossing are well-founded. But arms and terrorists are finding their way into Gaza anyway and Egypt’s move might, in the final analysis, constitute a less than unremittingly negative development for Israel, especially if Cairo maintains security control there and does not allow the unsupervised transfer of goods.Egypt’s change of policy, reopening the crossing to pedestrian traffic after a four-year closure, is a reflection of Egypt’s new orientation in the wake of president Hosni Mubarak’s ouster rather than a shift designed to advance Israeli interests in any way. Ahead of September’s parliamentary elections, Egyptian decision makers in the interim government are building bridges with the Muslim Brotherhood, which is expected to be a big winner at the polls. The warming of ties between Egypt and the Hamas, against the backdrop of the Muslim Brotherhood’s ascendancy, underlines the dangers lurking for Israel in the Arab Spring.One major negative consequence of the reopening of the Rafah crossing is readily foreseeable. It will boost Hamas’s falling popularity vis-a-vis Fatah. A Pew Research Center survey conducted in March and April found that support for Hamas had fallen among those living in Gaza to only 34 percent compared to 75% giving a positive rating to Fatah.
