I don’t think that the Supreme Court should have taken this case either the first time or the second time. The District Court was correct. This is a foreign policy issue, not a domestic legal issue. To me it indicates that for all Jews, including those on the Supreme Court, Israel is the country that comes first, before the United States. The expatriate American plaintiffs bringing this case live in Israel, not in America. Former White House chief of staff Raum Emanuel served in the Israeli army rather than the American army. Jews are racists at heart, and Supreme Court justices are no exception. American GIs have largely gotten over Vietnam and gone on with their lives. Jews are still consumed with World War II, the Holocaust and hatred of Germans, FDR (for not invading Europe sooner), and everything related to them.
I have just learned of the Supreme Court case Zivotofsky v Kerry (see http://www.scotusblog.com/2014/11/argument-preview-court-edges-close-to-the-mideast-cauldron/), which asks the State Department to list the country of birth as Israel for Americans born in Jerusalem. Currently the State Department lists the country as Jerusalem because of international disputes over the legal status of Jerusalem. The UN resolution creating Israel did not include Jerusalem as part of Israel. In the years since, Israel has conquered most of East and West Jerusalem, but international law has not recognized the authority that Israel has claimed. A number of UN resolutions have criticized Israel for its violation of international law. See http://www.un.org/Depts/dpi/palestine/ch12.pdf
During the Bush II administration Congress passed a law requiring the State Department to list Israel as the place of birth for people born in Jerusalem it they want it so listed. Bush signed the law but issued a signing statement saying he would not enforce this provision because it impinged on Presidential power.
The US has resisted recognizing Jerusalem as part of Israel, because Israel took it in violation of international law. Jews and Gentiles in Congress who are dependent on Jew money to get elected want the US to ignore international law and recognize Jerusalem as part of Israel. This Supreme Court case is another effort to reach the same result through another path.
