Why do muslim people in Syria and Iran keep keep killing one another and blowing stuff up?

Who un Iran killed who and where in Iran something blew up?

America don't like the leaders so they arm and train the rebels to kill them like Gaddafi and Hussein in Libya and Iraq they are dead Assad was more difficult because the armed and trained USA rebels became love child ISIS you know the wolf dressed up as grandma in Red Riding Hood that is your mommy USA

lets put it this way .. its REAL easy for any power with an organized intelligence service to place an operative with money and intel in a local muslim comunity and play on their religious beliefs .. all they need is money and an access to weapons .. the ideology is already primed to put radicalism into action .. i think this is exactly what happens .. arming and stoking their radicalism, especially directing it achieves the purposes of globalist western powers ...

You try walking a half a mile in their shoes. You have no idea what those people go through everyday. Somebody trying to kill them. The only other people that can possibly have any idea what they do go through are soldiers and blacks.

Very similar to why Protestants and Catholics used to do the same. Theists are suspicious of atheists but they reserve their extreme hatred for people who have similar but not quite identical beliefs. I don't get it, but it's true.
