I would say its the neo-cons that hijacked the Republicans with daddy bush that supported Israel..

With Bill Kristol being a leader in the neo-con/Zionist movement and founder of PNAC.

There is an easy reason why majority of Jews despise Trump and its because they are encoded by faith and history to hate any sort of nationalism.. because they can only thrive in a "multi-cultural" pushed environment...

Because no country, with their eyes wide open, when the curtain is pulled back, wants another culture running their governments through corporate lobbying money..

Nationalism is pretty much the opposite scenario on how jews can thrive in host nations.
