Critics of the cease-fire reached Wednesday between Hamas and Israel argue that little has changed. For now, they say, the Egypt-brokered de-escalation has merely placed a Band-Aid over a seeping wound, restoring the status quo established after Israel's Operation Cast Lead offensive of late 2008. Certainly, we may well see the return of airstrikes and rockets; the truce represents only a small first step toward a more durable solution. The nature of the agreement, however, points to a clear "Arab Spring truth" and a significant shift in regional dynamics: The international isolation of Hamas has ended.
