The United States retains major interests in Europe, evidenced by its conduct in numerous instances. Four indicators point to the Europe we can expect: Integration, the balance of European resources and the claims on them, Europe's relation to the U.S., and Europe's mood. Furthermore, change in Europe will not be a temporary phenomenon but rather a permanent state. In sum, the measure of Europe is both half full and half empty. American policy should support European integration and help create conditions that will enable the United States and Europe -- together with other allies -- to deal with a world that just won't stand still.
