Europe and U.S.
"This, in fact, is likely the largest point of disagreement -- and one that a President John Kerry likely would not have made smaller: Europeans today cannot imagine that the world might change. Maybe we don't want the world to change, because change can, of course, be dangerous. But in a country of immigrants like the United States, one actually pushes for change. In Mainz today, the stagnant Europeans came face to face with the dynamic Americans. We Europeans always want to have the world from yesterday, whereas the Americans strive for the world of tomorrow." From Der Spiegel.
