Up until the recent Spanish general election there was a Franco-German axis and a Brit, Italian and Spain as the other major axis. With a Spanish socialist government that is no longer the case, as you correctly point out. (British/Spanish feelings toward the thorny issue of Gibraltar seem to have improved following the change).
Britain appears to have some common cause with some of the new 'accession' states and her economy is in considerably better form than either France or Germany.
Blair is seemingly pro EU and pro Euro, but his chancellor or finance minister, Gordon Brown, seems very shy of joining the Euro (currency cabal). Brown appears to have a better understanding of the British people on this issue.
Significant differences within Europe seem to include viewing the EU as a common Market of sovereign states co-operating for the common good and those who see and want an increasingly binding Federal European state. A view most strongly held in Bonn and Paris. In the minds of some this is seen as a necessary counter-weight to power and influence of the United States. Blair is very opposed to this role for Europe. He, of course, sees himself as the bridge between Europe and the United States.
Part of the European super-state mentality is that it needs all the trappings necessary to fulfull such a role, common taxation, foreign policy and a united military force subject to a European and not NATO command and control structure. This latter point is one Blair is empactically against. Allies on this, as I recall, include Poland. France has long detached itself somewhat from NATO. A complication here is the United States has itself criticised Europe for not 'pulling' its weight in terms of its own defence. Some are saying if we have to provide and pay for a force within Europe, then that force should be subject to European rather than a transatlantic command and control structure.
(Even in Ireland there has been strong protests about the numbers of American troops coming through Shannon airport on the way to the Middle East. Unlike the Brits we have embraced the Euro, though. And been found to be best place to live in the world by the Economist Magazine).
As to POTUS visit to his northern neighbour, does he know the way or should someone lend him a map?
