Whether, or not, somebody on either side of a local civil war, did something (icky/horrendous/normal if we did it) does not constitute a existential threat on the US. Both sides in the conflict abhor us. Willing to take weapons and hard cash, of course, but when they get done liberating themselves, we will have another enemy. Who is in power because of us.
Please, can we just walk away from this? In our society, we've been killing each other over stupidity for a couple centuries. These ginks have been doing the same for MILLENNIA. We're not in the same class. Their rich guys can give our rich guys master classes, and charge what they want. We have no business there at all. If, against all odds, we actually fixed something, there would be another civil war in a month*, so nothing done. At all.


*But what if we fixed it?? Bullshit. We haven't fixed our own civil war in over a century. Their civil war is WAY beyond our grasp.
