Whether it be an escrow account or a budget commissioner, the latest demands by Germany show just how absurd negotiations over Greece's future have become. It is high time to bring an end to this tragicomedy.

For the past two years, Greece has wrangled with the euro-zone states and the International Monetary Fund (IMF) over its so-called "rescue." Austerity measures have been agreed to, aid has been paid and private creditors have been forced to accept "voluntary" debt haircuts. Despite all this, Greece is in even worse shape today than it was then. Its economy is shrinking, the debt ratio is rising and the country and its banks have been cut off from capital markets. There isn't even the slightest sign that the situation might improve. Something has gone very wrong with this rescue.

Yet none of the protagonists seem to have grasped this. They continue to negotiate as if things are business as usual, they let one "final ultimatum" after the other pass and they persistently fail to realize that their discussions have started to verge on the absurd. It would be a lot better to end this farce.

For weeks now, the Greek government has been negotiating with private creditors and the troika comprised of the IMF, European Union and European Central Bank (ECB) over a second bailout package. But it is already clear that this aid package will not save the country. It appears it will only delay a Greek insolvency -- and it will serve to create new hardships for the country's population.

It is time for politicians to admit that their carrot and stick strategy has failed. The idea that the country can be freed from its debt quagmire though austerity programs and aid pledges tied to conditions just isn't going to work. It won't even work if private creditors forgive part of the country's debt.
