No, that's still not true. The main goal was to negotiate with the Eurogroup and to have better austerity conditions, not to leave the EU for good. That's just what you interpreted.
Do you even realize that if Greece leaves, it would still have to accept the trading conditions of the EU? Do you realize that even Turkey could turn the trading conditions with Greece to their favor if it wasn't for the EU?? And finally, do you even consider that Greece has to pay much higher customs without the EU?
There is no economical benefit of a Grexit. I hope you are aware of that. Greece is too small and insignificant to negotiate good trading terms for themselves without the EU. They're just a small fish.
Let aside the billions that are floating into the Greek infrastructure to build motorways like the Egnatia Odos. Even the Turks envy us for such good streets. Founded by the EU.
No, your argument about the former Yugoslavian countries being in a better situation now is also debatable. Bosnia is a failed state and didn't recovered from the break up ever again. It has become the poorest country in the Balkans now. Montenegro doesn't even have an official currency, they use Euros instead. Same goes for Kosova, so much about their "independence" making it better for them. Croatia and Slovenia already joined the EU while Serbia and FYROM are still trying to get into it. Why do you think that is?
Seems like their "sovereignty" isn't that beneficial huh.
Btw, global influence doesn't mean that you need a strong military to have it although I'm not even talking about the military aspect. I'm talking about economical power, but I guess you didn't quite get what I mean. So I let the figures speak for me.
Population EU 508 million - Population UK 60 million - Population GR 11 million
GDP EU 19.2$ trillion - GDP UK 2.6$ trillion - GDP GR 287.11$ billion
Guess which one of the three has enough power to enforce their trading conditions on other countries around the globe.
It's the EU. The UK can't do that. It's too small. And Greece... well, without the EU Greece is almost insignificant. And talking about Greece... you blame the EU for the austerity??? Greece got itself into this situation. Year after year they wasted so much money given by the EU and now it's the EU's fault? No, Greece and only Greece is to blame for their lamogia.
Considering the migrant crisis the British should better keep their mouth shut. They had attacked Iraq and Lybia while Germany has not. Still, it's only Germany who's taking the refugees, while "Not so Great Britain" does nothing but complain. That's just as ridiculous as the whole EU-exit discussion.
