The Arabs have tried to eliminate on three occassions. They failed. It's way past their turn for the fate they wished for the Israelies. Live with it.
Ain't gonna happen. Israel is not the Soveit Union. Ethnic cleansing is not a feasible alternative for a first-world democracy like Israel, especially since Israel's sugar daddy, the US, would never stand for it. I suggest you stop living in your fantasy world.
Also, have you ever stopped to consider what kind of implications an ethnic cleansing of Palestinians would have for American interests? Do you really want to see Taliban-like regimes in countries like Jordan, Egypt, Yemen, and Kuwait?
When reason is not present, visceral hate seems to do very nicely for the Arab cause.
Resistance becomes futile only in the face of overwhelming force with the will to use it.
