Of course it is. Where did they get the money for the loans? Who loses if they don't get paid?
We don't have a European taxation system, an empowered European parliament, figurehead or any such thing.
The way things work in this case is that "The Troika" is a mechanism. As I said it's all foggy. But insisting that this Troika is ultimately the decision make, is independent and so forth is disingenuous, I think. Behind this troika is EU member state government that funded the laons, decided on the rules and will be on the hook if loans are defaulted on. Chief among them is Germany. It is their public interest at stake (sharing with other members, etc.). Also it is their banks (not only their) that these loans will go to repay, so it is also their economic interest. It is also their political traditions, biases and ideologies that are being largely represented by the "Troika"
The media depiction of Germans and Greeks is not just a made up populist Greek media invention. It's in the German media as well. Angela Merkel herself (with finance ministers of other member states taking a sort of deputy role) is speaking and acting a way that assumes this role.
To me, saying "germany" in this case is no different tan saying "The US" in the Afganistan War. You could be legalistic and say "International Security Assistance Force" or "Coalition." You could say NATO, of which the US are the biggest member. You might even say the "Afghan Transitional Administration and their allies" if you are willing to push it. But, we say the "US invasion/mission/force" as shorthand and that is more honest than all the rest. All those terms are mechanisms or sometimes euphemisms given form.
In any case, in my original comment it was a shorthand given that I don't know the ins and outs of this (purposely?) obtuse collection of acronyms and it wasn't particularly important to the comment.
I said "it was the troika (Germany, mostly) put the fallout on the German (and EU) public's tab."
What exactly are you claiming anyway? That germany isn't the key decision maker? They aren't they key lender in these troika bailout loans? That it isn't mostly the German public that will be liable for these loans when they are defaulted on?
I agree that this "Germany vs Greece" media dynamic is unhelpful. The media has been playing to nationalism in both countries. That stil doesn't mean pretending that these acronyms are real independent bodies is more honest.
