@hawkeye10,
That there are political frictions among the major EU powers concerning the efforts required to support the Euro, save the large French, German (and other) banks exposed to Greek debt; and their common interests in preserving their union, is hardly surprising. This aspect of the problem is simply the normal democratic process, and I don't believe it illustrates any weakness or danger to them or anyone. In short I believe Hawkeye's concerns miss the key issue and aren't of much lasting importance.
Instead, I am concerned that objectively the European nations will be unable to both preserve their social welfare systems (the European model they tout so much) and save the Euro, given the realities of their public debt, relative lack of economic growth in an increasingly competitive economic world, and increasingly unfavorable demographic situations. This is the key underlying issue. The political dialogue has not yet addressed this fundamental issue - that will probably come later after after the current debate is resolved and the remaining, underlying problems confront them.
A social/economic system that worked wonderfully well during the economic boom of 1950 - 1990, propelled in part by the large generation born after WWII and the early benefits of European economic union, no longer functions as it once did, now with sclerotic, over-regulated labor markets, chronic high unemployment among the young, accumulating public debt, and the shrinking and ageing populations resulting from profoundly changed demographics, particularly among the central and southern European nations.
