Where I come from, you bet it's treason. However, several years back, there was an entire thread about the use of treason verbally and in writing. While I don't remember much of the thread, other than the contentiousness, I did learn that treason is so narrowly defined, that it's next to impossible to indict, and convict.
So I guess that leaves sedition, something I was afraid to do when my dad was around!
But, based on your question, I'd be very surprised if you didn't already know this. Of all of the thoughts I've had about who Obama really is, and was, I honestly never thought he'd support ISIS. Is he a Shiite muslim, almost assuredly. Did he use his office to support Shiite causes, and Iran principally, his actions sure suggest that.
But ISIS was so vicious, so brutal to anyone who didn't think like they did/do (remind you of anyone rioting right now), that even I find it hard to believe that Obama and Jarrett legislatively supported those guys. Everything else, you bet.
As usual, terrific thoughts by you.
