@evan Obviously the specific-wording complaints could be a cover; if a resolution condemning both parties was put forward, would the US and UK have voted for it? Dunno. But it does sound like the wording included condemnation of IDF, rather than just calling for a truce, so maybe that's a real red line?
Also you gotta suspect all the other SC members knew beforehand that the US would use its veto; the resolution wasn't a surprise. Probably the point was more to apply big pressure in public.
