Israel could disappear under a mushroom cloud and US Jews would still unswervingly support the DemonRAT Party.
Hell, they’ll still be donating to DemonRAT candidates as they’re marched toward the ovens under the Hitllary! regime.
Its even that way in Israel between the upper social class Ashkenazim ("US" Northern European/Germanic) and the lower social class Sephardim (original Middle Eastern/Spanish).
It depends on what the definition of "Jew," is.
