"IMHO (3) is the most likely outcome, since the public war aims (stopping rocket and mortar fire) are so clearly impossible to achieve without killing absolutely everyone that they will have to pull out. Hamas will then launch a few rockets - which after all are extremely low tech and easy to fire off - and point out that they are still there, and have therefore won. They will then be massively boosted as a result, just as Hezbollah was in Lebanon. That could easily lead to Fatah being kicked out of the West Bank (despite all the Western support), and further problems for Mubarak in Egypt."
All the more reason for Israel, finally, to deliver the fait accompli to Hamas and it's sponsors....Live with us in peace, for this is what we desire and to which we commit ourselves. We will then live together as good neighbors should. Others have chosen to do so and it is preferable for all. It is your choice to make. If you choose otherwise, then we are not responsible for what shall follow. And then do one or the other.
The trouble with modern warfare, when it is necessary, when it is the last resort, it is not carried out properly.
to answer the question whether the Palestinians have rights...sadly, when they choose to live and act by the rule that their neighbor, The State of Israel, not only should be dissolved, but its people, men, women and children, be wiped from the face of the earth by any means, then the answer is no!
