ISIS uses American-made M83 to strike Russians
ISIS has seized numerous weapons from Iraqi forces the US foolishly armed when they ran remember. Have seen video and stills of ISIS with M-16s. Doesn't mean we sold them to them.
More likely they were supplied to them. Most likely by U.S. allies Saudi Arabia and Turkey.
More likely they ISIS ran off Iraqi or other US-armed forces and took their shit? Ya, it's more likely the US armed ISIS than ISIS defeated US-armed forces. You're in the running for biggest fool of today.
Some of that happened, but ISIS was well-funded & armed before that. Where did it get all its money and American weapons from? Just follow the money. That's where you'll find the truth
No, that's where you find loony-tune, delusional conspiracy theories.
As already correctly noted: like much of their other weapons, ISIS came into possession of this weapon after it was abandoned or otherwise misappropriated.
The thread premise is a lie, the US wasn't 'caught' giving anyone weapons, including ISIS.
