I must be naive; perhaps I'm dumb too. But, one thing I do not understand in about 99% of articles about Yemen War is the complete lack of analysis. In essence, everybody is just repeating the same exercise, over and over again.

Since WINEP (arguably: one of less-neutral observers around) published its 3-part analysis titled Gulf Coalition Operations in Yemen (Part 1), half a year ago, nobody at least attempted anything similar.

Why are all the other researchers and authors - no matter from where - (apparently) unable to do study the situation more closely, and explain what exactly went wrong? (For example: precisely what kind of a mistake Saudis and their allies did when starting this war?)

Particularly striking about this is: they obviously all still have plenty of customers buying their products - i.e. advice.
