The problem with Varoufakis plan was that he wanted to proceed to the issue of IOUs and also ‘seize the Bank of Greece from the ECB’. Most obviously without the consent of the Eurozone even though this would mean “unilateral actions.” Furthermore, Schaeuble would never accept Varoufakis’ IOUs for the simple reason that he wanted Greece to come to the brink of the financial collapse. Why do you think the 5 months negotiations did not reach anything and that all Greek proposals were rejected by Schaeuble right away, even before the whole PDF was through?
