As long as there are different religions in the world, there will never be an end to terrorism, now personally I don't have a religion, so I'm not trying to convert you or anything, but it's true. The basis of terrorism is dislike towards others so much that you feel you have to take action against them, what makes it terrorism though is the fact that usually it is extremists that carry out these actions. The majority of the time, this level of hatred is only caused by clashing beliefs, which is the same as clashing religions. The terrorists who carry out these acts are always extremely religious, and therefore believe that any others who believe otherwise should be killed, or 'cleansed' as it is often put. So basically, I could say that as long as there is conflict in the world (you can't please everyone after all), there will be no end to terrorism, but as religion is the biggest cause of conflict in the world, there will always be terrorism as long as there are different religions.
