He's a Holocaust denier from waaaay back. He presides over a regime that wants the Middle East's sole democracy (which, by no coincidence, is the world's only Jewish state) to disappear. There is neither free speech nor a free press in his "Palestine." So what on earth was Mahmoud Abbas doing in the line up of world leaders--five down from Israel's Netanyahu, no less--who stood side by side in Paris today?
Frankly, I think his appearance there was an insult to the memory of those who were slaughtered in Paris last week.
