Beyond this administration, the US government has a documented history of lying about the justification for military action. When people are being killed it is irresponsible to assume, with no evidence, that they are telling the truth this time.
I am not assuming the strikes are baseless, I am stating that there is no evidence for any basis, so discussing if they might be justified if some hypothetical evidence existed is pointless.
We've actually had multiple high profile intelligence leaks by the current admin because it's full of absolute idiots, and the leaks would indicate that they're about as smart as your average user on Twitter. Frankly if anyone believes their strikes have any sort of valid basis with all the leaks that have gone out then I would question their critical thinking ability.
