A comprehensive nuclear arms strategy

Vice President Joe Biden wrote an op-ed piece for today's Los Angeles Times. Here's an excerpt:

When I joined the Senate in 1973, crafting nuclear policy meant mastering arcane issues like nuclear stability and deterrence theory. With the end of the Cold War and a new relationship between our country and Russia, thankfully these subjects no longer dominate public discourse. Today, the danger of deliberate, global nuclear war has all but disappeared, but the nuclear threats we face from terrorists and non-nuclear states seeking to acquire such weapons are graver than ever.

On Tuesday, President Obama took an important step toward addressing these threats by releasing a plan that will reduce the role of nuclear weapons in our national security strategy while ensuring that our nuclear arsenal remains safe, secure and effective for as long as it is needed. The Nuclear Posture Review outlines a strategy, supported unanimously by the national security cabinet, for greater security from nuclear dangers and implements the agenda that President Obama first outlined in Prague just over a year ago to prevent the spread of nuclear weapons and to pursue the peace and security of a world without them.

This new strategy, a sharp departure from previous Nuclear Posture Reviews released in 2001 and 1994, leaves Cold War thinking behind. It recognizes that the greatest threat to U.S. and global security is no longer a nuclear exchange between nations, but nuclear terrorism by extremists and the spread of nuclear weapons to an increasing number of states. From now on, decisions about the number of weapons we have and how they are deployed will take nonproliferation and counter-terrorism into account, rather than being solely based on the objective of stable deterrence.
