Frank glad to read your opinion. Indeed from an individual standpoint you can´t control it. Most if not all of the attackers are locals and have a very serious criminal background and leading actually pointless lifes. I think they can´t give somehow a meaning to life and at a certain point in their young lifes step on the rollercoaster to hell, but they give an ideological twist to it and for that abuse a religion to justify and also give something (in their minds and those they hope to inspire) glorious to their actions. The aim is far from glorious, remains mainly suicide dragging as much people with it as possible how horrible that is to know, directly or being killed in a hail of bullets at the moment of arrest.
Once somebody has decided to end his life this way you can´t stop them changing their minds. These decisions are made individually or at least in a quite small circle. In a free world you can´t control everybodies mind to know the moment he or she is going to make this kind of decisions. However with attention of the people in the neighbourhood and security one can pick up the signal the moment that somebody is changing his behaviour. That´s the moment to come into action to come into contact / arrest the person. In some cases luckely a serious talk can be enough but in other cases there is needed more.
As said before the attackers have a serious criminal background and already know where they can get the weapons. I think the role of IS in the Middle East has more to do as far as I can understand, to give that ideological twist to their actions and is in the meanwhile ofcourse good for IS´s propaganda. Defeating IS is something else than how to handle the attackers here in Europe. IS requires military action, handling the attackers here is more about diplomacy, tact and social skills. I think again see the actions of these attackers more as an individual decision to make an end to their pointless lifes, not as part of a bigger well organized ideology. The ideology is ment more that they can give to themselves actually at least some sad meaning at the end of their addicted to violence short lifes. Competing with the attackers is pointless, you can´t compete with suicidal idiots.
Just stick to freedom, there is no other way. Seen the reactions of the Belgians mainly I can see on tv I have good hope they are very determined to keep following the path of freedom, the way they handle the situation is impressive. Sticking together, sharing emotions, trying to understand, finding ways what to do. It´s a huge challenge.....certainly not without mistakes..... but I have good hope. It will not be possible to avoid horror in the future again, but have good hope on the long run it will be reduced to an absolute minimum. I have good hope....
Politicians who say to solve this kind of problems with ease are completely underestimating the problem and making it only worse and much worse prepaired to damage the free world. For that reason I hope the elections of the US coming November will produce a worthy successor of Barack Obama. Maybe one can criticize Barack Obama in some respect, but with him America is great enough, no reason for improvements. The next president will have a huge influence how safe and free the world will be in the near future, I hope you will make the right decision.
I know there is a wider context of this problem and not so easy to describe in a few words. But this is anyway I want to say about this subject.
