Will Obama's "Global Nuclear Security Summit" be a farce or a force?

President Obama's planned Global Nuclear Security Summit is scheduled to take place in Washington, DC this coming April (no specific dates or location have yet been announced.) The theme of the summit is exploring ways to prevent terrorists from acquiring nuclear weapons. At least 40 countries along with international organizations are expected to participate. However, according to an outline on the Web site of the Center for Arms Control and Non-Proliferation, one of the goals of the summit is to "build confidence that the right to peaceful nuclear energy contained in Article IV of the NPT can be exercised safely." If this is the case, then the summit is likely not to see past the obvious flaw in Article IV which is precisely one of the easiest pathways used by terrorists to acquire nuclear materials in the first place.
