For all the so called Arab concern for the Palestinian plight, I don’t think they would hestitate to kill every single Palestinian (or Arab) in Israel if it meant riding Israel of the Jews. Or, for that matter, if it meant the land (including Jerusalem) would be unihabitable for the next few centuries. To them, it would be the price to pay for serving Allah’s will.
And for that matter, most Europeans would barely arch an eyebrow over it too.
The very same mullah said just that. I believe he said that the destruction of Israel would be worth the deaths of 300 million muslims. Of course, being iranian, having no love of arabs, I'm sure it wouldn't matter to him how many arabs were killed, he'd probably be OK with all of them dead.
