There is a world of difference, jake, between what the electorates of the various EU and Eurozone states want and what their political masters force upon them.
However else you look at it, Greece (and to a lesser but increasing degree Spain, Portugal and Ireland, soon to be joined by Cyprus) are economic colonies of Germany. The euro was made for and still exists for the benefit of Germany. Were it not for them it would never have been considered and even forgiving its introduction under false pretences, but for Germany it sould have been dead and buried by now. The stupid politicians in the subservient states who took their nations into the single currency saw no further than the end of their noses. Their arrogance and vanity which led them to believe they could introduce a single currency without a single government (against the advice of wiser counsel) was the policy of the madhouse. In fact, it is without doubt the most disastrous political decision, certainly in terms of damage done and the number of people affected, since WW2.
The German government will go to great lengths to preserve the euro. Its conditions are set ideally for them and nobody else. Their hope is that the sticking plasters will hold long enough for the good times of the first seven or eight years to return, the lesser states start borrowing more cash that they cannot afford to repay which they will spend on German goods. However, the choice for the eurozone is absolutely clear: they either fully integrate into a single fiscal union which will involve the movement of vast sums of cash from Germany to elsewhere (which the Germans will not countenance); or Greece and others default on their debts, leave the euro and rebuild their economies in their own sovereign currencies. There is no other alternative. Anything else is just fannying about and the end game cannot be put off much longer. The longer the decision is delayed the worse the situation will become and the more the economies of the UK, the eurozone, Europe and the rest of the world will suffer.
