" While it would have been straightforward, and perfectly legal, to allow Irish banks or the Greek state to default to their private creditors (so as to respect the no-bailout clause), the authorities’ guilty desire to bail out the German and French banks (without telling taxpayers that this was what they were doing) led to the need to violate the no-bailout rule by concocting another rule: the no-default rule, which was never part of Europe’s original set of rules. (...) Both the freshly minted no-default rule and the original no-bailout clause were political whims of the strong disguised as legal constraints upon the weak. In reality, the strong break their rules at will and concoct new rules whenever they think it suits them. "
