If you don't have enough integrity to admit this well known and well documented factMaybe you know things I am not aware of. Nevertheless, if you were to put a percentage on it, what ratio of the world's Muslim population, would you say, were jubilant?
You're changing the subject. You made a claim about the Palestinians, not the "world's Muslim population." It is well known that Palestinians celebrated en masse, with the possible exception of Hanan Aswari and some others bright enough to understand the implications. If you are not aware of the ample documentation of this fact, I suggest you do some research before you make the claim again.
A significant percentage of the "world's Muslims" did not celebrate the attack on the United States, although, disturbingly, a small but significant minority did, and a huge percentage of Palestinians certainly did.
