The debt-troubled nation was supposed to present the list to euro zone finance ministers on Friday, but it’s unlikely that a package will be agreed even by the end of the month.

As a result, in the next several weeks, the situation in Greece may deteriorate rapidly. The country could eventually fall out of the Euro, despite the intention on all sides to avoid that outcome.

This would likely plunge Greece into a renewal of the depression it was just exiting. Europe would suffer as well, although not as badly, with growth falling significantly. America would also be impacted, given that the European Union EU is our largest trading partner: we would lose jobs and profits as the EU imports less from us and as the U.S. dollar got even stronger, hurting our exports to all parts of the world. A more radicalized and alienated Greece could also become a serious geo-political nuisance for us, with close ties to Russia, its cultural cousin.

Though the timeline is uncertain, the odds are that a deal will be cut that avoids this very painful outcome, but there is a real possibility of disaster because of the conflicting views and political situations of the key parties.

The good news is that there is indeed a deal to be made. The broad outlines have been clear to experts for a couple of months. The interest rate Greece pays on its massive debt to the other nations in Europe would be cut to nearly zero and payments would be pushed out another decade or two, but there would be no reduction in the amount that would eventually need to be repaid. Europe would agree to accept Greek budgets that are a little less austere, but still are in surplus prior to the payment of interest. Greece would agree to further economic reforms, but Europe would allow more choice in which ones and how they are implemented, and even rollback of some very unpopular parts of prior agreements.

Importantly, Greece would have to accept that the generous funding is contingent on actually implementing agreed reforms and that this process would be monitored by the lenders.

Greece would have to compromise more than its European partners, but both sides would have to cross lines they have drawn in the sand. Europe would have to accept that the previous economic programs they foisted on Greece were flawed and substantial modifications needed. Greece would have to accept that most of their problems are their own fault and that borrowing hundreds of billions of euros from the rest of Europe inevitably requires handing over some control to the lenders and accepting painful reforms.

The core problem of the negotiations is that the new Syriza Party government in Greece views the world very differently from the governments in the rest of Europe. “Syriza” is a Greek acronym for “The Party of the Radical Left” and those last two words should be taken very seriously. Long-term members of Syriza, such as most of the members of Parliament, are suspicious of, or even actively hostile to, capitalism and the European system of economic governance. They do not see why Greece should follow a path of “reforms” that read to them like a right-wing wish list. Further, they have no previous governing experience and had no reasonable expectation of ever being in charge even 18 months ago. They have never gone through the internal fights that are necessary to move from a party of ideology to one of actual governance. As a result, their campaign promises were unrealistic and they do not have an internal consensus to back away from some of them.

Equally fundamentally, Greece is misreading its own importance to Europe. Yes, it would be very painful for its partners if Greece fell out of the Euro, since this would call the foundations of the monetary union into question and renew the Euro Crisis, and it is true the money could be found to accede to the Greek demands. However, Germany and much of the rest of Europe, believes that giving into what they see as unreasonable demands by a newly elected radical left government will guarantee that such governments arise in Spain (where Podemos is very much like Syriza) and eventually in other countries. This political contagion could be very damaging, leading to far worse risks than just Greece leaving the Euro.

For its part, Europe is being too rigid in its demands and has not accepted its share of the responsibility for the Greek economic and humanitarian disaster of the last few years that was caused in part by EU-mandated austerity programs. Europe does have to move too, just not nearly as far as the Greeks do.

My fear, and best guess, is that negotiations will have to break down and trigger damaging economic consequences in Greece and the rest of Europe before the two sides have the incentives and political rationale to agree to what should already have been agreed. The risk, of course, is that we could get the ever-growing economic and political damage, but not the eventual agreement. Europe has muddled through the earlier crisis rounds, and the ugly process is likely to work again, but this could be the time they fail to snatch compromise from the jaws of defeat.
