When I escaped from an abusive relationship that got VERY abusive as I was trying to leave, my ex went around telling everyone we knew that his abuse wasn't what it looked like and it was actually quite complicated. Just like Israel and its apologists are doing right now.
That's just what abusers do when people start calling their obvious abuse what it is, whether you're talking about interpersonal or international affairs. You see bloodthirsty swamp monsters like John Bolton using the "it's complicated" talking point all the time, because if you look at the raw data of the US war machine's behavior it's very clearly an extremely abusive and destructive force.
Imperial narrative managers work hard to make the depravity of the empire sound a lot more complicated than it is so that people will assume it's best left to the authorized "experts". And because of how locked down our rulers have the information ecosystem it often works; people look at things like Israel-Palestine and assume it MUST be very complicated, because if it wasn't then surely their government and their media would not be so supportive of Israel.
