I'm not even on the same continent as the USA, and I don't reckon belonging to or owning any secretaries of defense.
That's certainly a nice collection of links, yet don't seem to answer my question at all.
Also, claiming there are not freedom fighters in Syria is denying the whole civil uprising in 2011, and all of the utmost brutality and horrors perpetrated by the Assad regime against those protesters.
I'm not advocating funding terrorist groups, nor do I think the CIA and the Pentagon did a great job. (The whole intel/defense community is in shambles. Too much internal infighting, too few people taking responsibility, too much politics, funding issues, too much corruption because too much high-tech gadgets that must be maintained, produced, supported. You know.) But your worldview is overly simplistic if you think the story is that "a US plane was protecting terrorists". Those fighting on the ground probably have a very flawed sense of religion and what's right, how the world should be, but they're are currently fighting a fucking dictator. And that's a good thing.
The situaion around Raqqah (where Tabqah is) is basically the Rojava trying to purge ISIS from Raqqah while keeping Assad at bay at Tabqah.
see https://en.wikipedia.org/wiki/Rojava for who these folks are.
