These bailouts in the past were signed from the greece government in the best interest of its people. A lot of people make it seem that we (non-greece european) somewhat forced theses agreements onto greece. In fact these bailouts where were unpopular in Germany, because it cost us a lot of our money, we could have spent on infrastructure, education, etc.
Therefore I would love Greece to give up the Euro currency and leave the European Union, so that these other 18 countries don't feel any obligation anymore to transfer more money to greece.
I believe that Europe will be stronger that way. Because a vision of a truly united European Union can only be reached if all countries play by the same rules and abide to their agreements.
