Zionist bigot Josh Marshall, in defense of the unique values of American democracy, argues against dual citizenship.
An object lesson in moral conflict and cognitive dissonance.

-A Jewish state for a Jewish People, iff [if and only if] a German state for a German people.

-Beinart: "I'm not asking Israel to be Utopian... I'm not even asking it to allow full, equal citizenship to Arab Israelis, since that would require Israel no longer being a Jewish state. I'm actually pretty willing to compromise my liberalism for Israel's security and for its status as a Jewish state."

I'm tempted sometimes to argue that the US should restrict dual citizenship to citizens of countries that fit internationally recognized definitions of participatory democracy, but I'm not sure that the US would fit them.
