This was to be expected: Pakistani websites are blaming Mossad for the Mumbai attacks.
Russians have a small aphorism which makes fun of pathological Jew-haters which see "the Jews" as always responsible for everything:
If there is no water in the faucet - then the Jews must have drunk it
If there is water in the faucet - then the Jews must have peed in it
(it rhymes in Russian)
Seriously, it could have been Mossad, I am not saying it ain't so, but let's wait to get some facts before jumping to the usual knee jerk conclusions...
