The real consequence of this is that people will begin losing trust in the government and media institutions which support Israel, because without trust the empire can't propagandize people, and without the ability to propagandize us our rulers cannot rule. There's no risk for Israel of losing US backing due to the US government suddenly evolving a conscience or listening to its constituents, that won't happen, but losing control of the narrative poses a major problem for the empire. Someone's image is going to have to change, and those changes could end up benefiting Palestinians.
We're already seeing this narrative management campaign come into play as mainstream outlets are now permitting some serious criticisms of Israel. This is done cynically to prevent people from losing trust in propaganda institutions, but it also has real effects that can benefit real people. This is a good example of how expanding consciousness is always beneficial, even on the most depraved institutions. The more aware the public becomes of abusive imperial power dynamics, the less abuse the empire can get away with. The empire losing control of the narrative is always a good thing.
