You are correct, I am not an American citizen at all :) I guess what you said is true for any government but does it really matter? They get what they want in the end. Be it Alexander, FBI or someone from my country.
There is no "they". There are individuals who influence each other, each of whom may change their position depending on the position of others. History is replete with the consequences of changes inspired by advisers to advisers of leadership.
There is no guarantee that you can influence outcomes, but it is exceedingly likely that if you believe that you cannot influence outcomes, then you will not.
