Lets think about this ...
The war started about 6 years ago in 2010
The USA backed the rebels in 2011
On September 22, 2014, the United States, Bahrain, Jordan, Qatar, Saudi Arabia, and the United Arab Emirates began to strike targets of the Islamic State of Iraq and the Levant (ISIL) inside Syria,
Just our side not including Russia and Iran on Syria's side have been fighting for two years and some odd days and IS is still fighting back.
No Navy, no air force, no ground to air missiles, just a volunteer army of sorts and abandon weapons from the war in Iraq when they took over there.
Where do they get their supplies? How do they rearm?
Something doesn't add up to modern warfare with so much against IS that they still exsist is a wonder.
