Countering and preventing the threat of terrorism and violent extremism: from the international and european to the national and local levels

More than ever we see a nexus between internal and external security. Things happening abroad may have a direct impact on national security and public order and vice versa. Think for instance of the Turkish referendum and the protests of diaspora communities it spurred in the Netherlands and Germany. Since the terrorist threat clearly has a transboundary character and the efforts to spread extremist ideology, as well as to incite and to recruit, have a transboundary character it makes sense to also organise the counter approaches in a multilateral manner.
