Brother in law did some "time with the brass" as he calls it. His take was that the DOD, er DOW would, as an example, never acquire a fighter jet that "wouldn't target and kill a civilian airliner", citing that on 9/11 we literally almost did that. The DOW is acquiring instruments of war, which is probably unconformable for a lot of people to consider.
His conclusion was that the limits of use ought to be contractual, not baked into the LLM, which is where the fallout seems to be. He noted that the Pentagon has agreed to terms like that in the past.
To me, that seems like reasonable compromise for both parties, but both sides are so far entrenched now we're unlikely to see a compromise.
