Here is what I think is going to happen. Hamas will cease fire long enough for Israel to withdraw from Gaza. As soon as Israel withdraws from Gaza and frees the reserves they will go right back to what they were doing before the war started. They will test Israel's resolve by firing 1 or 2 rockets. How will Israel respond? Many will say that we can't go to war because of 2 rockets. Hamas will fire just enough to keep the people down South edgy but not enough to justify another full scale attack. They will also start smuggling weapons again. There is absolutely no reason to think that Egypt will do any better at stopping the smuggling now.
Last but not least, they will continue holding Gilad Shalit and use him as a bargaining chip.
In short, it looks like we are back to where we were 6 months ago.
