Currently it's the Zionist AbomiNation State that's getting its ass kicked. Maybe the Zionists should just start following the Torah - end their rebellion against the Almighty, and go back to the places that they're really from. That way, the Palestinians can get their land back, America can go back to being a Republic, and stop trying to take over the world, as an Empire - and we can all live happily ever after.
