Almost nothing. There was no public reaction countering Snowden’s targeting with US state violence, violence that forced him to flee, let alone any forced reduction in domestic spying or secret police activity. Both have probably increased. Nevertheless, self-serving narratives of being “the city on a hill”, a bastion of freedom and democracy, stay intact. It confirmed the biases of people who already knew this was likely happening, and those same people continue to be marginalized by an easily-propagandized public.
