In some ways, that is the genius of Pax Americana. Give people the idea that they have a voice to criticize and to change policy, and forever hold the moral high ground over regimes that don't bother to make that pretense.

Then have politicians run for office promising to address that. Once they're in office, they drop it completely, blaming bureaucracy and 'lack of political will'. Then voters start all over again, with heads held high on the belief that what they want could theoretically be possible with the next candidate. Or the one after that.

The Obama administration came into office on a promise to close Guantanamo, and offer a public option on healthcare. Neither came anywhere close to fruition.
