Regular readers of my blog will know that occasionally I wish to copy here something that's been written elsewhere, if I feel it's particularly apposite or well-written. I've been a fan of Konstantin Kisin's articles and podcasts for some time and feel that what follows is one of the best summaries of the Israel/Gaza war that I've read, using first-principles thinking, of which I'm a fan. And it happens to coincide with my own views, as they have developed since the first article I wrote about this. I recommend it to you.
