It's a good short term result- medium and long-term, this will surely have the effect little different from dousing the Euros with gas and setting it on fire- though who knows how things will specifically play out.

Personally I suspect Europe will not be escaping the US' thrall anytime soon (as a Canadian, same here). But the relevance of western Europe is no doubt only going to plummet from here onwards, and the current set of US puppets will probably have to be replaced in the decade or so to come- likely several times, though I can't see the puppet masters actually changing for now. Whatever it is, Europe's future looks more bleak, more unstable, and far less capable of filling its roles as imperial auxiliaries, as it has prior- and if the Europeans ever do actually start taking charge of their own destiny and realizing how badly Uncle Sam has screwed them over, then anything is possible.
