Hindu, Jewish, Buddhist, Sikh, or Christian lands/wealth aren't occupied nor attacked. At least, that's what an average Muslim observes. Many conflicts around the world also involve Islamic countries. From Palestine to Iraq everyone can relate to these conflicts. Scores of people die each day in these conflicts. Of course, there is hypocrisy in the world when it comes to resolving outstanding major conflicts. Heck, an occupying force blatantly murders women and children in broad daylight whilst the world looks the other way. Yes, I'm referring to Palestine. Hence, some so-called "Muslims" which are susceptible to violence are influenced. Some are simply rouge elements. Again, they belong to a specific ideology which has no commonality to any faith let alone Islam. The vast majority of Muslims don't relate nor condone violence in any form. Neither does the Islamic faith or any of its branches. Such outfits are a typical guerilla movement which use indiscriminate force to make their grievances heard. The only difference is that they abuse faith under the garb of injustice. Even their genuine grievances become null and void. After all, violence never resolves anything.
However, it's much more complicated than that. Violence in many countries around the world is also artificially fabricated. The violence is fabricated internally as well as externally. The Taliban, AQ, ISIL etc. are all militant groups which have received backing from the West in the past. This is no secret. They become "good" when their services are required. They become "bad" when they become a liability. This hypocrisy needs to stop both in the Islamic world as well as the West. Time has come to call a spade a spade. Also, the conflicts in the world need to be addressed in a fair manner which leaves no oxygen for grievances or radical thoughts.
