Europe's experiment with multiculturalism, or the side-by-side existence of different cultures, has failed throughout the continent. Integration requires a minimum basis of shared values, that is, a culture of mutual tolerance and respect - in other words, what constitutes the heart of European culture.

The conflict with Islam has, after all, existed throughout European history.

Only a Europe that is conscious of its own values can be both an economically strong and a morally and intellectually respected partner, and thereby extend its hospitality to others. It's a cultural disgrace that we are forced to identify no-go areas for foreigners.

Suicide attacks are the actions of losers who have nothing left to lose. In this case, Islam serves as a mask, a cover for desperation and nihilism, but not for religion.

Islam in the Arab world coexists with Indonesian, Pakistani and Turkish Islam. There is limited solidarity, even within the Arab world.

The distinction between the religious and secular orders is a fundamental aspect of Christianity. This distinction is an innovation compared to Islam and Judaism, and it is an advantage that has helped shape Europe.

The religious wars showed that the Christian faith was no longer Europe's unifying force. A new common ground was needed, and it was found in reason, which is something that is shared by all of mankind. This was one of the roots of the Enlightenment and its concept of universal human rights.
