It just seems to me, after one *ok a fraction of one* day of looking into it, that the majority Sunnis in most of the Middle East have been supremely frustrated trying to deal with their less conservative, more secular Shia neighbors. And it seems clear to me that America has at least attempted to enact a separation of church and state, even though those words do not appear in the constitution. It was in the First Amendment to the US Constitution that Congress was to "make no law respecting respecting an establishment of religion, or prohibiting the free exercise thereof". As wikipedia points out, lots of nations have this idea in their code, and there is a great range of shades of gray in its execution. Here in America we do fairly well, but nowhere near a perfect score. For one thing, the constitution has no control over the states and what local laws might be passed. Which may be how we have gigantic crosses along Interstate 5 in Washington State. Not so different from other places, where religion is supposed to guide personal and political life. Here we seem only able to elect Christian presidents. We like to think that we are above it, but we are surely not.
So I know I am rambling and I will call it quits. If you have an opinion about what is the crux of what is going on--in Syria, Turkey, Kurdistan, Iran, Iraq, Afghanistan, Saudi Arabia, Russia or any other involved party, feel free to comment and tell me! I'm building a mind map.
