Edit: I know recall JCS is reported to have said something like “its bullshit” about the Israeli operational plan/end state. But subsequent discussion focused instead on “can we”, not “how” or “should.”
And the current civilian administration is doing a pretty thorough job of eliminating anyone who _would_ point out previous lessons learned around strategic outcomes, going in to conflict necessitating clear & achievable exit criteria, creeping escalation, conflating use of force with success, etc.
Theres a reason everyone talked about “adults in the room” last time and anyone inclined to those kind of thoughts, or voicing the associated opinions, is absent now. And personally Id say that amplifies culpability, nit diminishes it.
