On September 11 last year international terrorism entered a new dimension.

We cannot allow violence from militant activists to dictate where and how democratically elected state leaders hold their meetings.

We can no longer apply the classic criteria to clearly determine whether and when we should use military force. We are waging war in Afghanistan, for example, but it's an asymmetrical war where the enemies are criminals instead of soldiers.

The vast majority of Muslims living here are peaceful citizens. Unfortunately, however, we also see religious and political fanaticism among Muslim groups in Germany.

It's a mistake to assume that Islamists always come from the slums. Indeed, many come from affluent families but for some reason just couldn't manage to integrate into Western society, even though they had good opportunities for advancement.

We feel very honored to have been offered the responsibility to host this great event, Berlin is a wonderful city that is developing at a tremendous rate, and this decision means that we can now prepare to welcome the world's best athletes to a fascinating place.

And now when we hear that Iran and Iraq plan to cooperate more closely and that a fundamentalist is coming to power in Tehran - a man about whom we cannot be sure that he is absolutely averse to terrorism - it is very worrisome.
