I think dismissing the connection between these acts and Islam is wrong.
Not all Musims are terrorists but a lot of terrorists are Muslim and they feel they are acting in the name of Islam when they carry out these attacks.
So its a relationship that needs confronting not ignoring.
Am going to go out on a wing and suggest some solutions:
1)Stop selling weapons to and or bombing far away countries.
2) Stop SA investing money in the spread of Islam in the west and stop doing business with them until they sort their human rights out.
3) Regulate what happens in Islamic churches and schools, hint of extremism shut them down.
4) Remove driving licences from criminals, this a more general suggestion. 5yr bans for all convicted nutters whether its a driving related offence or not.
5) (edit add)Licence internet users.
