This 16 November 2014 video from the USA says about itself:
Translated from NOS TV in the Netherlands today:
The terror threat in the Netherlands is still “substantial,” the National Coordinator against Terrorism (NCTV), Dick Schoof, writes in his latest report. The air attacks on targets of terrorist group IS in Syria and Iraq have not reduced the threat. On the contrary, the risk of attacks has increased because of that …
Jihadists are extra motivated by the air strikes to oppose the West, Schoof writes in the Terrorist Threat Assessment for the Netherlands. That applies not only to sympathizers of ISIS, but also for supporters of al-Nusra, the paramilitary group in Syria that is linked to al-Qaida.
The leader of al-Nusra warned in September 2014 that the air attacks could lead to attacks in the West. Until then, the group had never uttered a public threat against the West, the report says.
