Israeli-loving American politicians often claim that Arab countries
should give part of their land for the Palestinians to live on, so
that the übermensch could "live in peace" in the land that a
supernatural being - so they claim - promised to them.

Why not establish a Jewish state in the continental United States?
There they could live in the safe bosom of America, far away from
the evils of the world!

And why not two? One for the orthodox Jews and one for the
secular ones (so that problem would be solved too). In the
traditional American way, you could make them tourist attractions.
Let´s say a modern New Jerusalem for the secular Jews and a
for example 1st century BC or AD Jerusalem for the orthodox ones.
All in the open prairies of the west!
