Uneasy nuptials

In principle, the idea of a "two state solution," one state for each of the combatants to an age-old conflict, "living side-by-side in peace and security," seems idyllic. But, as everyone knows, on the way to the nuptials a lot can happen. The bride and groom can have second thoughts, and the mother-in-law can interfere.
What happens if, after Israel accepts a "two state solution" under the Road Map and Annapolis plans, currently being pushed by Pres. Obama, Secty of State Hillary Clinton and George Mitchell on his trip to the Middle East, Hamas takes over the PA, either in a coup or in an election. After all, Israel withdrew from Gaza and instead of improved relations with the Palestinians things got a lot worse. The Bush Administration, pushing it's policy of democracy in the Arab world, said we should not be afraid of an election in the PA and what did we get, a Hamas Government, followed by a coup in Gaza against the Fatah-controlled PA. As people have said many times, an election does not make a democracy, Hitler had an election and so did Stalin, many times. Being elected did not stop Hamas security forces from throwing Fatah PA forces off tall buildings, as well as torturing and executing hundreds of them. Do you think they are going to voluntarily give up power in Gaza?
Given this situation, of a Hamas-controlled terrorist enclave next to Israel, the leader of which, Ismail Haniyeh, this weekend stated that Hamas will "never" recognize Israel's existence, should Israel simply accept this situation. And should Israel officially endorse the "two state" plan and then what if Hamas takes over the West Bank, as there is clearly a likelihood, notwithstanding both Fatah's and Israel's opposition, then what?
Having a Palestinian terrorist entity in the West Bank would be much more dangerous for Israel than in Gaza, given the proximity to the population centers of Israel along the coastal plain and Ben Gurion Airport, not to mention Jerusalem and everything of vital security importance to the survival of Israel. Before exposing us to such a situation, Israel needs certain assurances, but can these be added after a Palestinian State, of uncertain provenance, has been agreed to. It seems to me that the situation dictates a high degree of caution. You wouldn't buy "a pig in a poke" and neither should we, to satisfy other people's appetites. After all, even the mother-in-law can't guarantee a happy outcome after the wedding has taken place.
