The unknown biases issue has no real solution. In this same example if instead of something simple like snow in the background, it turned out that the photographs of wolves were taken using zoom lenses (since photogs don’t want to get near wild animals) while the dog photos were closeup and the ML was really just training to recognize subtle photographic artifacts caused by the zoom lenses, this would be extremely difficult to detect let alone prove.
And actual material support was affected how?
You definitely didn’t. American support for Israel is so well entrenched that is has actual strategic depth. That includes ensuring that the political path of least resistance is to support Israel absolutely, so Trump does. It’s just easiest. All you’ve done is look at words with no actual action behind them . All material support has remained completely stable.
