Berlusconi is a good survivor too, because he was vanquished by markets and that was even clearer than in Greece. And, before, he seemed unbeatable... so, his quick fall was a fine event in 2011.
To be fair, the first signs of his demise were the massive electoral defeats of may-june 2011. He was clearly aging, losing its fantastic PR skills, failing to grasp the trends in public opinion, and desperately gripping to a political reality that was crumbling from everywhere. In short, he became a prisoner of the delusions of his past glory, at the exact moment when such glory was fading away. Had he been 2001's Berlusconi, and had Italy's public opinion been what it was in 2001, he would most probably have kept enough political capital to hold on despite the markets. Even though markets were the decisive factor, every shot he had taken beforehand (sex scandals, electoral debacles, near-collapse of his parliamentary majority) played a key role. At least, that's my reading of events.
