America became great because it was populated by those same europeans. That jews were destroying Europe did not make America great. Both continents could have prospered simultaneously. Development and prosperity are not a zero sum game. Wealth is created through work. In fact having wealthy nations to trade with and collaborate with would have only increased america's development. If europe had been free of Jews and returned to producing technology it would have accelerated technological advancement for the entire world. America would learn from what europe did and leapfrog it.
