There are still deep-seated structural problems that threaten the economic balance in the world: Between the United States and China, for example, but also within Europe. We have taken a few steps toward taming the financial markets, but we haven't come nearly far enough to rule out a repetition of the crisis.

Greece will not manage to get back on its feet without restructuring its debt. There is no way around it. The country's creditors will have to reduce a portion of its debts by extending maturity dates, lowering interest rates or giving them what's called a 'haircut' in financial jargon.

You can't exactly bake a man to your specifications. Most of all, one shouldn't alienate a candidate. A hybrid of Einstein, Tarzan and Inge Meysel doesn't exist. Besides, the images of politicians in the media aren't always accurate. I've had my share of experiences in that regard.

The U.S. will lose its status as the superpower of the world financial system. The world will become multi-polar.

You can't let a candidate run for too long. He will be dragged along, cut apart, put back together and ripped to shreds again - from both the political opponents and the media.

I would happily help to turn the stone being thrown at me into a boomerang.

If I had political responsibility, I would want to prepare for a plan B that would foresee that the European currency union, that the eurozone, no longer necessarily consists of 17 member states. And that means to make provisions so that other countries are not pulled into the maelstrom through contagion.
