I think the correct way of viewing this war is around internal White House power games.
I don't think Trump himself particularly cares about Iran (or indeed Israel) - as in I don't think he has strong heartfelt views or moral convictions that cause him to act one way or the other in the strategic sense.
But there are those in the White House who do.
My impression from afar is that JD Vance wouldn't have been very supportive of this war, but his faction lost some power after the success of the Venezuelan adventure.
I think that particular move was Marco Rubio, but I'm not sure he would have been crazy enough to make the jump from that working to thinking that war with Iran was a good idea.
It doesn't seem to have been Stephen Millar's idea either.
So maybe it was a bunch or fairly random people from the pro-Netanyahu faction in the WHite House (not sure of names? Maybe Hegseth?) who really believed that this would be a quick bombing attack to take out the Supreme Leader and degrade some Iranian military capabilities, and it would be quickly over?
Maybe it was just Pete Hegseth trying to seem extra macho and people actually listened?
Writing it down makes it clear how very confusing this it. Maybe no one actually wanted this and they just went along because no one was actively saying it was dumb?
Of those options I'd guess Hedgseth as he seems to be the one cheering the war and also using Christian rhetoric. Trump has also suggested he may have relied on Hedgseths advice to scapegoats Hedgseth in recent days..
Yes reading more of recent news coverage I think this is the likely explanation.

It is possible that the current war launched by the US Department of War by the chairman of the Board of Peace is the result of the Abilene Paradox.[1]
However, this vile collection of idiotic thugs more likely reached a Dunning-Krugerian consensus that this would be a quick and easy win. They all think themselves smarter and even nobler than everyone else.
They are however simply more remorselessly corrupt than most people imagined.
