After the arrest of a Syrian man suspected of planning a terrorist attack in Berlin, intelligence services and security experts are warning of a dangerous trend: estimates suggest that up to 500 million Muslims across the world hold radical or extremist views. Fanatical Muslims seek to impose Islam globally — even by force, if necessary.

The arrest in Berlin of a Syrian man suspected of planning an Islamist attack once again serves as a warning. According to information from security sources, German investigators have concrete intelligence concerning an Islamist Islamist threat

Arab intelligence services estimate hundreds of thousands of extremists

Intelligence data — particularly from Arab countries — has made clear the scale of the danger.

According to these reports, between 15 and 25 percent of the world’s Muslim population can be considered radical or extremist. That represents between 300 and 500 million people out of a global Muslim population of around two billion.

This figure includes not only those willing to use violence, but also those who reject Western ways of life or who seek to impose Islam worldwide.

Hasnain Kazim, in an interview with Welt, put it bluntly:

“If we trust the data provided by intelligence services, then we are talking about 300 to 500 million Muslims worldwide who hold radical or extremist views.”

Europe in danger

European security authorities are preparing for further Islamist acts of violence.

Representatives of radical Islam are expected to plan terrorist attacks more frequently in the future.

– according to security sources. Jewish institutions are seen as particularly at risk, which is why Germany is currently stepping up security measures. Several communities are erecting new walls and barriers to protect themselves from potential attacks.

Can the attacks be prevented?

The latest arrests and checks involving Islamist suspects are only the beginning, experts say. There is a need for tighter monitoring at sites of security importance and for open debate about the ideological roots of the threat. Such measures cannot entirely prevent attacks, but experts believe they could at least reduce their frequency.

While the majority of Muslims live peacefully, intelligence data still points to a dangerous potential: a fanatical minority seeks to impose Islam across the world — even by force, if deemed necessary.
