Hamas are religious fanatics. The leadership is living large in Doha. Israel will never allow a two state solution. That's why they backed Hamas instead of secular Arafat.Then that's another reason for Hamas to surrender - to stop this no-evidence conspiracy theory of Israel support the terrorist group that burns its childrend alive.
Also, if Hamas stands in the way of a two-state solution (it does) and you support a two-state solution, shouldn't you want them to surrender as much as Deadstick should?
