It is a GRAVE ERROR to think of Saudi Arabia as a friendly state.  This is where schools teach children they must kill all non-believers.  Americans may not realize it, but teaching killing to children is WORSE than the Iranian political chant, "Death to America."

Did USA go with wrong ally?  Did DoD and our intelligence get it wrong?

The Muslim world is essentially Sunni and Shia.

"Sunnis and Shia in the Middle East"

There are more than 1.5 billion Muslims and about 20% of them live in the Middle East and North Africa

"Shia make up roughly 10% of all Muslims, and globally their population is estimated between 154 to 200 million, according to a 2009 report from the Pew Forum. Iran has the largest Shia majority, with more than 66 million making up nearly 90% of the population. Shia are also in the majority in Iraq and Bahrain.Dec 19, 2013"

Does the American Government, and our hired "experts," really understand the Middle Eastern courtiers, and ISIS?

Are Unintended Consequences at work here?

What is going on?

Is this an Iranian "False Flag?"  It is hard to imagine Iranians conducting a False Flag..

Is it possible the United States will never defeat ISIS because we do not realize how to defeat ISIS? 

Americans do not take Tweety tweets seriously, but we are supposed to do so.  Yet we take Iran leaders chant "Death to America" LITERALLY, as a real threat?  It is foolish and ignorant to do so.  Read up on your history of the Middle East and you will understand this is but a slogan against ALL WESTEN INTRUSION INTO THE CULTURE OF IRAN AND MIDDLE EASTERM COUNTRIES.

American leaders and people who have studied Iran and the Middle East, in general, understand the chant is like giving the middle finger to us for meddled endlessly in their government.
