We are facing a whole collection of crisis-like developments that we have to watch closely. But we also have to be careful what we point to as crisis indicators.

If the Schengen system (of border-free travel) is destroyed, Europe will be seriously endangered politically and economically. That is why we Europeans have to invest billions in Turkey, Libya, Jordan and other countries in the region as quickly as possible everybody as much as they can.

The goal of European unification can only be achieved if everyone participates, perhaps with exceptions in some areas. Not all countries are part of monetary union, and not all are in the Schengen area. But the fundamental goal should be to keep everyone on board.

Reliability is the precondition for trust.

I would caution against fueling cheap populism. First of all, every German who has spent a vacation in Greece knows that the standard of living there isn't higher than it is in Germany. Second, Greece is paying a high price for European assistance.

I can't think of many other laws we might need. For now, though, we'll be talking to German Muslims over issues of coexistence.

When it comes to training imams, one needs a partner. But if we want the mosques to preach peaceful coexistence, we will have to do something about it. One goal of the conference is to find a partner for the training of imams and teachers of Islam in schools.
