The previous rules didn't allow countries to have debts of over 60% GDP and budget deficits of over 3%. Who bothered with that?

So, now the alcoholic promises really hard to obey the similar rules.

If a country is in breach and basically says "sod you" when the EU tries to reprimand them, then what? They get thrown out of the EU? I doubt it. Many countries are agreeing to this as they have no intention of obeying the rules if they happen to be in breach.
