These are things no social democrat, or even a conservative, would ever say. The Italian Marxist Constanzo Preve made the point that former left-wingers who disintegrate internally tend to stop believing in anything.
The second possibility is that he had already taken the decision to sign up to the Third Memorandum, but needed a display of bravery up to the last moment, to legitimize it—so that he could say, ‘You see, I’ve used all the weapons I had, and I couldn’t get more than this; there is no alternative.’ So, those were the intentions.
But it’s a fundamental mistake for formations of the radical left to agree to a line that is merely complementary to social democracy. We don’t need radical-left parties to make deals with social democracy to limit foreclosures, raise the minimum wage by €50, cancel some redundancies in the public sector, and so on. If we really think that’s the best we can get, we should operate within the framework of social democracy, and try to obtain some concrete improvements. But for a political current that supposedly has an alternative vision for society, accepting this as the horizon can amount to giving up on that vision.
