Israel's action must be decisive to be effective. A cease-fire or truce will only allow Hamas to grow stronger. Perhaps the bigger problem for Israel is the apparent decline in support from other nations who now see her as the aggressor. This puts Israel in the uncomfortable position of having to eliminate this problem before public perception declines further.
At least a recent British newspaper article reported from both sides equally. Forget about having "major" U.S. news organizations doing that.
