Most countries around the world have no problem extraditing their own criminals for crimes committed elsewhere (including the US), but it seems like countries like the United States and Russia fear that extraditing their war criminals would set a precedent that could cause their entire governments to collapse.

Is it the people that make up the system, or the system that makes the people? In a country with rule of law, any individual in the government should be extraditable (for valid reasons) without it being a threat to the overall system.
