Nuclear Weapons At The End Of 2007

There is supposed to be a Nuclear Non-Proliferation Treaty which limits the countries possessing nuclear weapons to the 5 which had them at the time the treaty was signed, and it is the responsibility of these countries to work to abolish their own stockpiles.

As a leader of the world, it is the responsibility of the USA to lead and administer this treaty. How has it done? Lousy...considering the down side. If you look at what may be lost, the USA had done lousy recently. Consider a piece from 2003:

The Nuclear Nonproliferation Treaty: History and Current Problems
 "...The NPT has in fact suffered major blows. Since 1991, uranium enrichment, plutonium separation, and other possibly weapons-related activities that Iraq, North Korea, and Iran hid from IAEA inspectors have been discovered. Iraq’s weapons program was found after the 1991 Persian Gulf War thanks to UN Security Council orders demanding more intrusive inspections than were then required by IAEA inspection standards. North Korea’s weapons program later became known through intelligence, IAEA inspections, and North Korea’s own admissions. The IAEA’s discovery of Iran’s failure to disclose experiments with plutonium separation and uranium enrichment to inspectors has recently led to a standoff with Tehran. " (paragraphing my own)

Consider these: one country was a hermit and outcast since WWII, the other two had engaged in a serious war between themselves, and one of them was openly supported by the USA. Instead of ending their emnity, the USA allowed it to increase.
North Korea is also a member of the Axis of Evil, a sobriquet which is not exactly equivalent to Blue Riband and meriting a jolly welcome to the White House. North Korea is also a part of the Korea model that Mr. Bush puts forward as an exemplar for Iraq. Furthermore, it is doubtful that any progress would have been made with North Korea without the active support of China.
The White House attempted bombast and threats and axis of evil and would not have gotten to second base without China. And so it goes.  

At this time, I repeat my prescription for Mr. Bush and Mr. Cheney: "It is not fit you should sit here any longer—you have sat too long for any good you have been doing lately. You shall now give place to better men...

Depart, I say, and let us have done with you. Go!"
