The truck attack on a mosque two weeks ago in Finsbury Park, London, represented two disturbing recent trends in terrorism. First, the manner of attack: There have been six major truck attacks in Western nations since December of last year—Nice, the Berlin Christmas Market, London Bridge, Westminster, Stockholm, and Finsbury Park. Law enforcement and intelligence agencies are scrambling to find an answer to these kinds of attacks. Second, the profiles of the terrorists: The perpetrators have largely been either citizens or permanent residents from within the societies they attack.
Increasingly, the danger to a community or a country comes from inside rather than outside its borders. The solution favored by far right politicians and their supporters worldwide is to mitigate the risk of attack by preventing the movement and settlement of Muslims in western nations. However, most terrorism experts agree that this does not address the problem and is in many ways counter-productive.
