What is so wrong with identifying foremost as an American?
First, while this may not bother some, doing so is accepting the Galut (exile).
To answer your first point, so what if one is accepting the Galut? Jews lived outside of Israel for two thousand years. In that period, Jews often learned the languages of their host countries and made innumerable contributions to society and culture. Certain Sephardic Jews even rose to the highest levels of government and held the most prestigious jobs, all while making notable contributions to the Jewish religion.
And during those 2 thousand years how much persecution did we go through? We don't belong in the Galut we belong in our land, the land of Israel.
Why didn't the Jews who were expelled from Spain in 1492 go to Israel? Why didn't the Jews living in the Pale go to Israel before the 1880's? Yes, persecution is horrible but it wasn't horrible enough to compel Jews to go to their G-d-given land until the Holocaust. Even then, the preferred destination was the United States! The promised land, with streets paved in gold!
And Germany was paved in gold at a time too.....
At those times immigration to Israel was difficult because it was barren or immigration was forbidden by the occupying force. America, so far has been one of the best places for the Jews, at least in a physical sense. In a spiritual sense it has been murder. Assimilation is higher than ever and Jews increasingly are not willing to recognize that they are Jews, intermarriage is at an all time high, and the non-Orthodox movements are allowing Jews to compromise on their Judaism.
I believe intermarriage is terrible and I have a strong ethnic obligation to preserve this heritage. However, the Jewish people are not going away in America any time soon. There are 6.4 million Jews in America. Additionally, the Haredim, who never intermarry, have increased by over 100,000 in the last 6 years.
Germany was also a place where Jews prospered, but we are best in Israel. Of the 6.4 million how many are "Reformed" or non-observant "Conservative"? These movements contain a large portion of that 6.4 million and those 2 movements will fade....
Yes, Israel is ideally the best place Jews for a whole host of reasons. AND I fully support the Jews of Judea and Samaria in their struggle against the leftist Israeli establishment, the Nazified EU, the Jew-hating UN, and the Arabs.
HOWEVER, my personal place is in the United States so long as it lives up to the ideals of our founding fathers and I will do what it takes to protect those ideals. That is my responsibility as an American, even if preempts the 'covenant of the forefathers'.
