Among the things that make the U.S. different from Britain, that Roberts does not mention, is the character of the U.S. as a nation of immigrants. As true today as it was for millions who came to these shores from Ellis Island at the turn of the century. This makes for a much more adaptable society with different strains of thinking. Another point that makes the U.S. different is that it has striven to be an anticolonial power in its policies- working to ease the transition to independence of countries in the former French and British empires. The U.S. business and economic system has worked to bring development and economic progress in all parts of the world, as a partner in contrast to a colonial power. In this sense the U.S. has a very different character and a different capability for renewal than the empires of an earlier period- and new basis for belief in itself renewable from period to period.
