As for the actual perpetrators of the carnage being experienced in Syria, it no doubt originates from the philosophy and actions of US neocons who set in motion the destruction of the peoples of the Middle East and North Africa (you recall, don't you, General Wesley Clark stating that the Neocons planned to destroy 7 countries in 5 years?).
While citizens in the Middle East and North Africa are being bombed and otherwise killed and maimed, the Neocons sleep each night in their very warm beds. While citizens in the Middle East and North Africa suffer death, destruction and chaos each and every day of their very sad days, the Neocons dine in fancy dining rooms at their Think Tanks. While the citizens of the Middle East and North Africa lose their livelihoods, the Neocons are handsomely remunerated by the Think Tanks that employ them.
As for where the Think Tanks that employ the Neocons get their financial support, you can thank the American taxpayer. The American taxpayer pays his taxes, Congress uses this taxpayer money to support the arms industry, and the arms industry uses some of this taxpayer money to support Think Tanks -- it is called a beneficial circle (you can also use a naughty term, but we won't go there). And, to spread the free taxpayer money around, to grease the skids, so to speak, the arms industry contributes funds to the Congress persons who made their abundant revenue stream, in the first place, possible. In addition, the arms industry uses some taxpayer money to buy advertising in the mainstream media (you need good press, you know). Everyone enjoying the swill of the arms industry (and security industry} gets wealthier and wealthier, while Middle East and North African citizens get killed, maimed and, if lucky enough to survive, lose their livelihoods.
Well, God has a funny way of working. He has decided to let this go on until, in the end, there is a nuclear war between the US and Russia, and several of the Russian and Chinese submarines off the two coasts let it rip. And there you go, life for the Neocons comes to an inglourius end. No more substantial income working for the Think Tanks, no more fancy lunches in the Think Tank dining rooms, and, as a matter of fact, no more anything. There is a problem though - God does not save the rest of us.
