The current policy of just trying to capture the perpetrators isn't good enough.
Terrorist cells need nipping in the bud.
1.To do this many sting operations need to be mounted. Preferably by fellow muslims.
2. There should be a hotline for people who think they are being targeted by the extremists. They should be given anonymity and counselling. Preferably by fellow muslims who can see murder is wrong. The ring leaders would be put in jail.
3. For every death caused by terrorists there should be a doctrine of collective guilt. So if a Lybian gets found out after killing then 100 Lybians should be sent back for each victim after paying compensation to the victims and their families.
Trump may just have the balls to do something on these lines rather than accuse the wrong countries.
The Europeans haven't got what it takes until other extremists get elected.
Why not start by actually applying the law when people - including Muslims - do commit crimes ?
The truth is : most of these suicide bombers were "known" by some law enforcement because of some stuff they did before. Obviously, some law enforcement people , for whatever reason ( including corruption), p-r-e-f-e-r not to record, nor many times bring some criminals to face the law.
Java : do remember that many people had ancestors that have had some traumatic pasts. Yes, some were more traumatic than others - I am thinking here of victims of génocides, at any moment in history. However, it is better to give historical facts, and explain the emotional effects on the victims and their descents. Because, more often than not, most people have no idea that some people carry, générations after générations, the memory (?) of their ancestors disasters.
Now, if I remember well, many Americans are descendents of very empoverished people who fled Europe so as to avoid starvation ( potatoe famine in Ireland, land clearing by the English aristocracy in Scotland, fear of serious religious persecution in Holland, etc.). How comes, Americans have came to peace with the disasters that their ancestors went through in Europe? May be this is where, Java, you could learn something there.
