It's not just the tactics of removing the tyrannical idiot from power, it's also a matter of not propping him up in the first place. Kings might fight amongst themselves, but all of them prop up the popular delusion of their "divine right to rule". When anyone salutes the US flag, they're also saluting the flag of Nazi Germany and Soviet Russia and North Korea and Libya, etc, etc, etc. All governments grow from the same seed, human ignorance - they just grow differently in different kinds of soil.
