Do you have any actual examples of political history being actively censored by western models? Or are we just doing hypotheticals for fun?
Still, if you ask ChatGPT or Claude details on what's going on in the western bank, Israel and Gaza, there's a specific viewpoint being pushed. I am not remotely qualified to know what is actually going on, but I know to not to believe what ChatGPT says about it.
Your example is already under dispute by actual humans. Expecting non-AGI to get it right is not realistic.
