In 2006, I had a debate with Tariq Ramadan, the author of Western Muslims and the future of Islam. In the hypothetical event of a war between Egypt and Switzerland, for which community would he be prepared to die, I asked him.
Mr Ramadan has dual citizenship. He's an Egyptian by birth and a Swiss by naturalisation. His response was one of rage on different levels. Above all I think he was outraged that one should ask such a question. He refused to answer.
Mr Ramadan, like many other Muslims, may have two or more citizenships. From all that he expresses both in person and on paper, it is clear that his loyalty, above all, is to Islam. I do not doubt that he would die for Islam, like most Muslims, and that's his prerogative. But what European countries have done is give citizenship to individuals who feel no obligation to share in their societies for better or for worse, for richer or for poorer and in the event of a catastrophe, sacrifice themselves.
