The first bill introduced by the new Democratic leadership of the House of Representatives during their “100 Hours” crusade was H.R.1, Implementing the 9/11 Commission Recommendations Act of 2007. Contained in this massive bill are Sections 1221 and 1222 dealing with the Proliferation Security Initiative (PSI). The PSI is one of the most successful diplomatic and security measures devised by the Bush Administration against the spread of weapons of mass destruction (WMD) and their delivery systems. 

The PSI is an international coalition that was composed initially of Australia, France, Germany, Italy, Japan, the Netherlands, Poland, Portugal, Spain, Singapore, Norway, Canada and the United Kingdom. It now numbers over 70 member states.

It is not just non-proliferation; it is counter-proliferation.  Full Article
