Of course they'd say that - their job is to instigate a war; they're hardly going to come out and say "this looks like it might have been a rerun of the Gulg of Tonkin"
Like Hans Blix - they're there to provide legitimacy for what's about to come, not to actually look too hard (even though Blix failed that brief).
TBH - I've no clue whatsoever, but all the sabre rattling is coming from one side; and a president who's desperate for anything to distract his domestic audience, and has been looking to have a war started late 2019 for the last 2 years - just a matter of whether it was going to be Iran, Venezuela or N Korea.
