Who determined the PSI Statement of Interdiction Principles?
The Statement of Interdiction Principles (SOP) was agreed among the founding PSI countries on September 4, 2003. We believe the SOP is a straightforward set of principles that countries should support, and in fact, responses worldwide indicate this is the case. As a practical matter, it would not have been possible to develop the PSI in a way that allowed it to come forward quickly yet still involve all interested states. While the Principles have been agreed, the PSI is a dynamic initiative. If countries have ideas that are not reflected in the SOP that would contribute to a more robust, effective initiative, we want to hear from them. In that way, the PSI is an initiative open to contributions from all states that want to support interdiction efforts.
