Their goal?
"To fight zionism, eliminate the zionist presence, and liberate Palestine".
Their method?
The same method used to destroy Czechoslovakia -- first get it into indefensible borders by speaking about "peace", then demand the rest / start the war, as per Arafat's "staged plan" of 1974.
Their defenders?
Lots of little Chamberlines -- those who naively think that if you give these genocidal terrorists what they want now, they won't ask for more later. These folks are known as "moderates" or "supporters of the peace process".
Also, lots of little Quislings -- those who rather like the idea of the genocidal terrorists winning against the Jewish state, and support them out of inner conviction. These are known as the "anti-zionists".
Sorry to intrude with the truth, and the obvious truth at that, into all the wonderful peace-making and stuff that's going around, but still.
