Many have been citing a pasuk from Mishlei

- namely, 24:17 - בִּנְפֹל אוֹיִבְךָ אַל-תִּשְׂמָח - in reference to Arafat's death.

In light of the treatment he has received by much of the media and many world leaders, I think Mishlei 24:24 is more relevant:

אֹמֵר, לְרָשָׁע--צַדִּיק אָתָּה: יִקְּבֻהוּ עַמִּים; יִזְעָמוּהוּ לְאֻמִּים.
"He that saith unto the wicked: 'Thou art righteous', peoples shall curse him, nations shall execrate him."
