This week the world watched as Greece continued its fight for economic survival. Armed with the Greek people's resounding "no" vote on yet another round of economy-killing austerity measures, Prime Minister Tsipras went back to the negotiating table with EU negotiators. But the rescue package he presented to the Greek Parliament on Friday was a mixed bag: while it includes fresh loans, it also comes with the kind of destructive elements -- like regressive taxes and pension cuts -- that already tanked the Greek economy. As the 28 EU leaders meet today, it's clear that Greece isn't fighting mindless austerity just for Greece, but also for the rest of Europe. The Greek public's bold stance has galvanized anti-austerity groups across Europe. It's like a proxy fight in a new cold war -- but this one isn't East vs. West, it's the failed past vs. a sustainable future.
