On the one hand this may have been the time to do it, there was a confluence of factors that seemed to make Iran vulnerable.
But it seems weird to take a victory lap on most of the objectives. No one thought the USA was incapable of bombing Iran back to the Stone Age. So while I think some of the points about the region abandoning Iran are cogent, it wasn’t the first year after starting the war anyone was worried about, it was the next twenty.
