I think the problem is with the religion knowm as Islam. In fact it's not a religion in the actual sense of the word- its a cult. A cult based in medieval and tribal beleif. Muslims are actually frustrated people, they have nothing to be proud of , no global achievement no service for the humanity, nothing. Where the other nations are doing research in medicines,life saving drugs,ever new technolgies, space research, arts,,,muslims have nothing to do except envying other people and supported by their one book ( as if it's a over used master key('Kunji') to pass all exams)they go violent. And this is not a recent phenomenon, it happened throughout the history.
And about Jehad and violence...Imagine if the Christians of 150 odd countries...or the Hindu- Buddhists of India- China- Japan- Korea- Vietnam- Thailand- Burma etc. unite and float extremist forces like the Muslims...within a year there will not be a single Muslim on the face of earth to talk about their religion!They want that? Nothing is one sided man! Newton told so 5 centuries back. - Deep
