You talk about bankers bribing or blackmailing them into taking loans. Then you come up with the companies. These are completely different from each other.

Right, so Germany just sold X billions of submarines they never intend to deliver working either way to Greece, which has no income, no cash flow & no reserves to speak off. How do they get paid off like they ask ? Ho well, they push a loan on Greece : http://www.theguardian.com/world/2012/apr/19/greece-military-spending-debt-crisis

However this was only a tiny part of the Greek spending.

Uh, no. We're talking about nearly a hundred billion € of debts.

This is nothing that would ruin your budget.

Weeeeeeeeellll... when it start running to that much & you have to push back retirement 20 years for some people because you can't even pay said retirement after the latest weapon orders...

The greek army always tried to match turkeys power, a ridiculous idea.

Well; from greece's point of view, of course it's not germany that's going to be on the front line if turkey start putting a dozen F35 in northern cyprus. Or at least it's how i heard it.

Greece ran a deficit that was beyond good and evil for years

Yes, but half the blame is probably from neighboring major powers that bribed the country to death then blame it for it's corruption.

They ran ridiculously overpriced olympic games because why not?

That definitely was the straw that broke the camel back. But that's not the cause of the issue.

Again, even if bribery is involved : Nobody forced them to take loans.

Well, apart those that told them "pay up now, or face defaut. [If defaut, you are evicted from the EU.]"
