Why in the last decade have we seen a succession of Israeli prime ministers and opposition figures but only Mr. Arafat alone?
Term limits.
Not true, there are no term limits in Israel, the reason is free and democratic elections, the people didn't like the way the Prime Minister was handling affairs so they voted him out.
Arafat on the other hand seems to be President for life (as is Hosni Mubarak, Assad, King Abdullah, Saddam, Qaddafi, etc, and every other ruler in the Arab world)
What would the world think if Mr. Sharon displayed a revolver and then attempted to strike one of his ministers at a Cabinet meeting?
That he was dangerously unbalanced.
Very good, this is exactly what Yasir Arafat did. Of course this isn't recent behavior, he came to the UN General Assembly in 1976 with a pistol.
