Then they haven't gone far enough. If they are going to do what they should, they should take Mecca, destroy the black rock and shrine, and build a nice Jewish house of worship. Then they should take the House of Saud hostage, and shoot them in order of precedence, until they get one to convert to Judaism, whom they should put on the throne. Then they should round up the population, inform them that they are now Jewish, and that if they revert to Islam they will get the same punishment as now would be given a Moslem who converted to Judaism.
After that, they should get mean.
That's pretty funny, even though I think you probably mean it.
It is funny, except that this is exactly what the Palestinians have in mind for Israel, as they have stated, and is what the Islamists have in mind for us. What's sauce for the goose is sauce for the gander.
