Well, personally, I believe that's definitely a possibility as to why there is war in the world. What with the different religions and what not in the world, there's bound to be some sort of beef between countries that are predominantly a certain religion and an opposing religion. If you ask me, it's foolish that it even IS a possibility simply because it's not that hard to coexist with one another. Apparently those countries who are prejudiced against an opposing religious country hasn't caught on. But whatever tickles their peaches, you know?
