Hoosier's note: "Dijsselbloem" - "Diesel Bomb"
In my opinion, this is just a Poker Game between Greece and Troika.
I believe Greece wants to stay in the Eurozone, but on MUCH better terms. Although Germany has been saying that it is ready to let Greece go but I believe Germany is also acutely aware of the possibility of a total breakdown of the Eurozone should Greece leave.
I think GREXIT is highly unlikely.
