Why does it sucks ? What I can say you is that it is a mondial success.
It's really very shocking what happened today but I don't think that you can blame whole Islam community for something what only several people did.
What you suggest here?
To put all Muslims in the Europe to prison?
Do you think such radical solutions will change or solve anything?
We need to fight with terrorism and ISIS, not Islam.
Islam and ISIS are not tge same.
In fact, ISIS started war also against Islam, as you can see from many terrorist attacks also in Afghanistan, Pakistan, Iraq etc.
We should fight with Muslims against ISIS.
Problem is that we're no more facing organised commandos sent by the Islamic State but lone wolves. What has to be done is to close all coranic churchs and radical and illegal prayer places. Those, to be closed, need ultra-violent positions.
