All previous attempts at total nuclear disarmament have failed, as strategic logic and state interest have prevailed over wishful thinking. A similar fate awaits Global Zero, the newest disarmament movement, for similar reasons.

Michael A. Levi discusses the New START treaty.

Jonathan Pearl cautions that the Obama administration should be careful not to place too much weight on the new START treaty as a stepping stone toward deep nuclear force reductions and global nuclear disarmament.

Micah Zenko argues that controlling U.S. and Russian supplies of tactical nuclear weapons would reduce the potential for nuclear terrorism, decrease the perceived threat to U.S. allies, and maintain momentum toward President Obama's goal of a world without nuclear weapons.

The independent Arms Control Association (ACA) today released the 2009-2010 report card on nuclear nonproliferation and disarmament, concluding that the current global institutions are "neither on the verge of crumbling nor on the cusp of success."

What comes after the New START treaty? A follow-on treaty should limit the U.S. and Russia to 1,000 strategic and tactical nuclear weapons, says this CFR report.

Micah Zenko asks, "What if Americans were the ones without nuclear weapons, and a well-stocked Iran was insisting that the United States couldn't have such weapons?"

Sheila A. Smith says that Japan must go beyond its commitment to reduce its own nuclear weapons and play a more active global role in persuading others to abandon their use.

Sheila A. Smith says the nuclear summit offers Japan the opportunity to voice its long held aspirations for a nuclear free world.

The signing of a new strategic nuclear agreement with Russia bolsters U.S. president Barack Obama's diplomatic credentials and opens a new chapter on arms control, but domestic political challenges await, says CFR's Charles Kupchan.
