Correct me if I am wrong, Greece wanted to leave as they were not prepared for the austerity measures imposed on them by EU and IMF, but they were blackmailed or bribed back into EU, or they would suffer many more years of struggle.
Part of the reason that Greece wanted to Leave the Euro, is the very reason that the Eurozone is struggling, and why we'll do okay. They can't devalue the Euro in order to kick start their economy. The Pound has dropped against the Dollar and the Euro and our exports are now cheaper, so our economy will take off again.
Okay, to be fair over things, they can't afford to repay their loans so that's an even bigger reason to get out, but the IMF has suggested they write off some of the loans, but the Germans have refused to let the ECB do that - which is a bit hypocritical since the Greeks let the Germans off half of their loans after WW11.
And I'm not sure who made the comments about the EU's made the biggest contribution to peace and democracy in Europe, when it was Nato that's kept the peace, and the EU that's trashed democracy.
