An answer to the comments. I am in no way minimizing the horrific cost of civilian deaths and wording should have been stronger but the Project Syndicate Editor changed my wording to "not particularly high" which is too mild but that is the prerogative of editors I guess. My point is only to highlight that the numbers (given the 18 months time and the fact that unconventional warfare practiced by the Houthis makes them use civilians as cover) do not prove that Saudi is intentionally targeting civilians. That is why I give an example of Syria where the intentional targeting of civilians has created hundreds of thousands of casualties.
