Two arguments predominate. One, which I have heard mentioned for quite some time, is that in moving rapidly, as we will over the next five to six years, to a Union of 25 member states, we will need to consolidate the changes made and bed them down and that we do not need to move forward as fast. The other argument has been made by federalists. They argue that Europe must continue to integrate. It must quicken the pace of integration and, in a sense, create a federal Europe.
