What is happening is NATO has decided to protect the Turkish citizens from reprisals from Assad. So they are putting the Patriot batteries along the entire border between Turkey and Syria. To begin with, DC does not know its tail from its nose. That should have been done before they decided to topple Assad. Stupid. Stupid. Stupid. So the Russians find out that the batteries on going in, they tell Assad. So Assad decides to ready his chemical weapons. Both the Russians, Iranians and Syrians have deduced that the patriot missile emplacement will be a precursor to an invasion of Syria by NATO forces.
So Obama gets a call on the golf course, telling him about the chemical weapons activity due to the patriot missile decision. So he gets all riled up and warns Assad that using the chemical WMD would cross the red line. Both Obama and Hillary fail to mention that their decision to actually protect the Turkish citizens from their invasion of Syria, caused the Chemicals to be mixed in the first place. We are being led by buffoons. They always lie to us. And they are gonna get a whole lot of people killed.
No Rational Global Strategist would do some of what they are doing.
Assad shelled Turkey and killed Turkish citizens. These attacks on a NATO member justifies NATO action to defend itself. That is the reason for the Patriot missiles.
