I think you hit the nail on the head. Greece could bring back the drachma with ruble backing or backed by russian gold as a transitional measure. Then they can do their own QE to their hearts content. In exchange Russia gets a mediterranean port.
You are correct. in many ways the Greek situation is like the proverbial Trojan Horse against the ECB , European banks, IMF, EU Commission and the fiat mechanism in general. The danger is not Greece per say but the repercussions throughout Europe. Spain and Italy are next and when they fall, party’s over.
