Star, while I generally love you, Israel was NOT born out of the Holocaust. The modern Zionist movement started a century before, and the Jewish state was promised to the Zionists and the already Jewish majority in Jerusalem in the early parts of the 20th century before World War ONE.
It is the Arab narrative, and that of Obama, that claims Israel is the result of some kind of collective guilt. That story makes deligitimzing it all the easier. Don't fall for that.
