Germany 'enforced' the borowing rates? Let's look a few years back. The rating agencies rated all kinds of junk very high. The banks all over the place where very creative with products hiding the risks. When Germany was asking for tighter regulations we were ignored or laughed at. Now the Germans simply demand that the lessons are learned and we see structural reforms - reforms which can not be done by just throwing more money at countries high in debt.
This is not "a few years back" - this clusterfuck has been brewing since year 2000 with the euribor. At that point several countries needed high rates to stop their overheating borrowing and they were given a shower of petrol to stop their fires.
