Government should be judged by how well it meets its legitimate objectives. Good government is that which most effectively secures the rights of the people and the fruits of their labor, promotes their happiness, and does their will.
"The care of human life and happiness and not their destruction is the first and only legitimate object of good government." --Thomas Jefferson to Maryland Republicans, 1809. ME 16:359
I believe the US falls short of the definition of good government when it comes to its own citizens, and more so when acting abroad. Collataral damage, Kazi and the US orchestrated Afghan elections......!
I have to unfortunately admit that no other country gets close either!
