The 2014 ISIS invasion of Syria and Iraq was commanded from a Joint Strike Command-CIA bunker in Jordan.

CENTCOM provided direct air support the entire time to prevent Syria from closing its border crossings with Jordan, Turkey and Iraq. This allowed free movement across the borders.

There were threads about it at the time.

Obama assembled over 250,000 covert fighters in the "caliphate" at its peak. The largest illegal army ever fielded by the USA. Orders of magnitude worse than Reagan's Contra armies.

Al Nusra is basically the British, French, Israeli, US pretending to be REBELS doing the actual frontline fighting in Syria. ISIS was the occupation force who carried put the mass genocide akin to the Nazi SS in Poland and USSR in 1941 to 1945.

The US and other NATO and GCC states continue to block international tribunals against their ISIS army.

Now CENTCOM openly operates as "Coalition Forces" basically holding all the land they helped ISIS grab.

In many instances, British, French and American special ops dressed up in those black dresses pretending to be "ISIS/Daesh"
