So, is our government really justified in making alarming noises about the Iranian government... or are they part of the problem?
What we need is something more clear cut. If, for instance, a government were to indefinitely detain political prisoners without trial, or commit war crimes, or tie people's hands behind their back and then systematically execute them... well, that would be reason enough for regime change, right?!
"This and no other is the root from which a tyrant springs -- when he first appears he is a protector." - Plato
"When the tyrant has disposed of foreign enemies by conquest or treaty, and there is nothing more to fear from them, then he is always stirring up some war or other, in order that the people may require a leader." - Plato
