Zionists and Trump

There is something going on in US political culture about Trump: as much as Trump is championing the most extremist and violent trends of Zionism (and Zionism is by definition extremist and violent), American Zionists are rather split: some are rushing to identity with him and his administration, while many others (from the left and the right and center) are expressing nervousness and even concern about his administration.  Not sure whether this will have an impact on Trump's foreign policies.
