Like other groups there are observant and nonobservant, or secular, Jewish people. Second, amongst the observant there are those that believe in transcendent enduring moral order and those that hold their faith as a loose collection of enlightenment sentiment. This group can be also divided by the division outlined by Thomas Sowell in A Conflict of Visions as those that believe in the Constrained and the Unconstrained vision of man. The belief in the perfectibility of man and that our social orders can be constructed to adapt such a construct, denying heavenly Grace, works out to about the same division.
The same question can be asked of Christians and to expect Jewish people to always come down on the momentary side of who looks to be doing the better job of friendship to a Jewish state lacks belief in Jewish Americans largely being Americans first, which I believe is the case. Israel is very important to many Jews, but to pretend it is the sum total of their values is simplistic.
