Am I connecting the dots correctly? 

Iraq and Iran are Shiit, hated by the Suuni of Saudi Arabia to whom we just sold 100 BILLION dollars (= a thousand million dollars, one hundred times over -- thanks Mr. President). 

And ISIS or ISIL (or whatever) are also Suuni, therefore likely backed by Saudi Arabia (think Catholics and Protestants in the UK when thinking Shiit and Sunny). 

So did we just sell 100 billion dollars of weapons to the backers of  world's most active terrorist group?
