Gaza truce seemed too good to be true

News that Palestinian militants have violated the five-day-old Gaza ceasefire should come as no surprise to anyone. Missiles fired from Gaza struck the Israeli border city of Sderot, injuring two Israelis. The missiles apparently were retaliation for the killing Tuesday of an Islamic Jihad member by Israeli troops in the West Bank, which is not part of the ceasefire. Israel and Hamas, which controls the Gaza Strip, urged restraint on behalf of the half-dozen or so groups involved in the long-running Arab-Israeli conflict. Hamas took over the Gaza territory in a 2006 war with the Palestinian Authority, which controls the West Bank. Hopefully, the isolated missile firings will not scuttle efforts to resolve the short-term crisis in Gaza and get more relief to beleaguered residents. Keeping Arab and Israeli groups sworn to kill each other from actually killing each other is a huge undertaking, probably beyond the abilities of those involved. But resolving the long-term situation, which seems to get more complex every year, will be even more complex.
