Support for Hamas will evaporate once the economic situation of the Palestinians improves. I would propose slowly easing restrictions on traveling and at checkpoints, allowing the Palestinians to get legitimate employment and goods and services they require. I think that Palestinians would also be less supportive of Hamas if Israel's attacks against Gaza stop, seeing as collateral damage from these attacks only serve to strengthen Hamas' position. Ideally, a mutual ceasfire can be achieved.1) Popular support of Hamas must be removed from the Palestinian people. Hamas gains its strength from The People; in them, it "swims as though a fish in water," as Mao Zedong so aptly put it. If the average Palestinian can be convinced that he has more to gain from supporting something else than supporting Hamas, then their power will slowly be eroded. The question is, then, with what methods can the average Palestinian be taken away from Hamas, what offers, what opportunities, what solutions can we offer or can be offered that will both be to Joe Palestinian's advantage to support, and be apparent enough for him to easily see? This is one question we must answer.
It all depends on the willingness of both sides to make concessions. These proposals seem sensible though.2) Israel must give up some of its land gained in the Six-Day War. You simply cannot house, much less support, 1.5 million people in as small an area as the Gaza Strip. Israel must surrender some of its land to a future Palestinian state.
3) A compromise must be reached concerning the sovereignty of the city of Jerusalem. Perhaps it can be administered as a constitutionally neutral city-state, with free passage for all who wish to visit the Holy City. It should be a demilitarized zone, with an aura of peace comparable to its spiritual value. Given the "progressive attitude" of Islam, this may be difficult to engineer, but perhaps made somewhat easier by the fact that Israel controls the city.
I think if Israel made some concessions (such as giving up the Golan Heights, already in your previous recommendation), Syria would be willing to recognize the state of Israel.4) Syria must recognize Israeli sovereignty. Of Israel's former adversaries, it is the only nation that has yet to do so.
