Here's Rafael Behr making the argument that whatever we may think of Keir Starmer's position on the US/Israeli attack on Iran, in reality no position that he took was likely to be right.... or widely popular.
You can judge for yourself the fairness of that assessment, but I think the argument has *some* validity, given the diplomatic & political situation the UK has put itself in over the last decade.
