The IDF assassinated one of the military commanders for Hamas using a missile, a commander who was moderate and could get the other factions of Hamas and Islamic Jihad to stop firing rockets into Israel. Just a few hours before being killed, he looked at the ceasefire terms and had said that he supported the plan.
Also, this same situation that we have today has happened before in 2002. They almost got a ceasefire, but right before the last military commander looked at the ceasefire and OKed it, an Israeli F-16 dropped a bomb and killed him, his wife, children, and seven neighbors.
Here is some information about the 2002 assassination from the only American who was on the team. http://www.informationclearinghouse.info/article33057.htm
There are no moderates in Hamas only a naive chump or fellow traveler would pretend there are. Hamas's stated goal is the destruction of Israel, that is the fabric of their existence, well that and returning the whole are to the medieval era. Hamas is a organization that terrorize its own people in Gaza.
Hamas can have peace anytime they want it... but then they do not want it.
