The mistake by Greece was that it's not big enough. In this sense, Spain is not Greece. With Too Big To Fail status, Spain can afford to bluff, to dominate and prevail at the negotiation table. Unless and until the conditions for rescue are watered down enough, Spain has no incentive to apply or, even after accepting money with pride and grace, to actually comply with conditions.
This is due to the philosophically flawed design of OMT, as is the case for all euro rescue plans so far -- or one might say even the euro itself -- not the moral quality of any individual or group.
So the reality is the supposed conditions for OMT have no teeth. They are there only to stop German Bundesbank President Jens Weidmann from resigning, at least for now, causing a huge embarrassment to ECB and serious damage to its credibility and effectiveness, as reported by Reuters in a fascinating account of events leading to the OMT announcement.
The ECB is destined to capitulate every time. The reluctance may be genuine on the individual level, but borders on scam in the sense that the bank has no choice from day one. The German people will be reminded of various previous capitulations on Greece and Italy, only this time on a much bigger scale.How long will Germans endure such Outright Monetary Thievery I do not know. It's just a step down the road leading to the inevitable "Gerxit."
