1. Actually, Israel has never been forced to negotiate a peace deal, either with the Palestinians, nor with any other Arab countries. At least not by those combatants. If they were "forced" to negotiate, it was by the U.S. and other Allies, who explained to Israel that aid that they were receiving might disappear if peace was not made. However, because the Arabs really don't want "peace", any negotiation is really just about a delaying tactic until the Arabs can again mass manpower and weapons to continue the fight. It's been that way from the beginning, and I don't see it changing any time soon.
Why wasn't it 'forced by its allies' before the Intifada wore Israel down?? Nonsense. Israel have always ignored Palestinians altogether until they took the matter to their hands and a certain pressure was applied to Israeli society by the Intifada. Israeli society couldn't tolerate the price of Intifada and the Israeli Government had to do something. When the Intifada stopped, Israel stalled the peace process. Israel will never give Palestinians a thing as it sees itself too strong. Only resistance reminds Israelis that for peace and security, Israel has to give something in return for the Palestinians. Else, Israelis will vote in another government that can give them security. It's no secret now that Israel thinks it can get security by waging more wars. But wars give more legitimacy to resistance as it further convinces people of Israel's ill intentions and lack of interest in peace.
2. Oh, I thought you were referring to President Bush.
Trust me.. He's worse. Ask Drew.
3. The difference of course between Hamas and "Arab armies" is that during the 1967 War, those same Arab armies fought a conventional war, out in the open, like traditional armies, against a tiny little country, whose only option was to fight or die. That little country beat the shit out of all those Arab countries, because they had to. When the dust had settled, Israel had won lands that hadn't been theirs, that they were then forced to relinquish, again by the U.S. and also Russia. Hamas, like the Viet Cong, fight their gorilla war from the midst of the local population, but unlike the Viet Cong, Hamas attacks civilians, and the Palestinians appear to be too stupid to realize that by allowing these attacks to come from their locations, retribution against these very areas, in the hopes of killing the Hamas fighters, will happen. That the Palestinians haven't rebelled against Hamas, for causing their problems, is amazing to me. But it's certainly a window into the Arab soul. And by the way, you certainly don't believe that those rockets fired into Israel are actually "home made", do you? Get serious.
If Hamas were/had a conventional army, they'd act like one. They're a resistance group that wants freedom and liberation for its people from the mightiest army in the region. They use what they can get. And yes, most of their rockets are home-made/cooked from sugar, oil and fertilizers (I'm not sure.. but that's how the rumour goes). What you don't know is 90% of Hamas operations are against Israeli soldiers. It's not Hamas' fault that you don't know/don't want to know this.
Palestinians want freedom and a state they can call theirs. It's a basic right. Peace talks didn't give them anything, not even hope. The resistance did. That's why they don't rebel against Hamas (plus they trust Hamas for running the government way better than pro-Israel, corrupt Fatah. plus Hamas runs many charities, hospitals,.. ie serves the society in the best way possible). Hamas members are not alien to Palestinian society, they're people's brothers, father's, sons, etc. If you have a fighter in the family, you'd protect him the way you protect other non-combatant members of the family.
