What surpises me about the whole Netherland thing...is the speed of events. The attacks on the Mosques...took only a couple of days. The reaction of the police to the explosives found...apparently have set off a national high police posture. The US state department has declared this weekend a period for Americans not to travel around the Hague. This didn't take months after the van Gogh killing...it took mere days.
Here in Germany, there is a high watch upon what is happening in the Netherlands. If it triggers any anti-Muslim efforts...then revenge will occur...and the right-wing in Germany benefits greatly.
If this weekend goes off without any violence...then the whole situation may simple tail off. But if more violence occurs...I'd watch for additional situations in Denmark and Germany by next week. This thing has a opportunity to take off.
What is said quite often in the last few days about the attacks on mosques (police believe they have been attacked by right wing extremists) is the fact that in Holland (and in Germany even more I believe) extreme right is not allowed to have a political voice. And since there is no political outlet, people take action in their own hands.
I'm no expert but hey, sounds plausible.
It looks like politics and police are trying to show to the public that they are going to stop muslim extremism with all means available... several arrests... new legislation... raid on a PKK training camp at a holiday farm (sic!).
It looks like the situation is cooling down at the moment and we have to wait and see for the next x years what the results will be.
