Round peg, square hole. The IRA wanted freedom and a nation of their own, they didn't want to all die in the process. Hamas on the other hand likes the idea of dying and have their own country but they refuse to sit down and shut up.
No, the IRA wanted to create a Catholic state and then expel all the Irish who had collaborated with Britain. It was a religiously fanatic movement whose members shot women and children, and committed many of the worst acts of torture in the English speaking world during that time period.
This entire discussion is premised on the belief that Palestinians have no rights. If you accept that Palestinians presumptively have the same rights as everyone else in the world, there is absolutely no justifying what is going on.
But folks in America and Israel don't believe that, and so when agricola points out that killing people for "looking suspicious" is crazy, that's just rejected out of hand. And at the same time as the Palestinians are not recognized to have any rights, we're all demanding that they refrain from any violence and just play nice.
I predict two long term consequences of this war:
1. Upwards of 1000 Palestinians dead.
2. Israel/US friendly government in Egypt will collapse. Maybe in Jordan too.
