The real issue of dealing with proliferation of weapons of mass destruction: nuclear, chemical or biological is: What is your tolerance for risk? And my tolerance for risk for WMD proliferation is pretty close to zero. Because otherwise, we and our allies are at the mercy of regimes like Ahmadinejad and the mullahs in Tehran, or Kim Jong Il and the Hitler-in-the-bunker mentality in Pyongyang, or others who don't share our calculus on the value of human life.
Although we refer to the International Criminal Court, the real problem is the prosecutor, because it's the prosecutor who decides who to investigate and what cases to bring. This court fundamentally embodied a potential for abuse of governmental power that I felt was inconsistent with being a free person - and [it was] inconsistent for a free country like the United States to subscribe to it.
By creating a prosecutor who is overseen over by a court, they are melding executive and judicial power in a way that can lead to terrible abuses - as the founders of America understood full well. It's why they created a system of separated powers - to set up a constitutional mechanism that would enhance freedom, by making sure that no one's accumulation of power could predominate over [that of] others.
