Which part of the title indicates that everyone walked out? I assumed it was merely some of the cohort.
Technically, that just means at least two people at the Pentagon who qualify as leaders disagreed.
But it seems like broad opinion.
The reader may wish the disagreement wasn’t documented at all, because it doesn’t meet their own personal editorial standards, and they like telling someone they don’t pay how to do their jobs.
But factually, there’s nothing incorrect about what was observed and reported.
