“Obama’s new budget plan includes a little-noted sea change in U.S. nuclear policy, and a step towards his vision of a denuclearized world. It provides no funding for the Reliable Replacement Warhead program, created to design a new generation of long-lasting nuclear weapons that don’t need to be tested. (The military is worried that a nuclear test moratorium in effect since 1992 might endanger the reliability of an aging US arsenal.) But this spring Obama issued a bold call for a world free of nuclear weapons, and part of that vision entails leading by example. That means halting programs that expand the American nuclear stockpile. For the past two budget years the Democratic Congress has refused to fund the Bush-era program. But Obama’s budget kills the National Nuclear Security Administration program once and for all.
“My colleagues just stared at that line,” says Joe Cirincione, a longtime nonproliferation expert and president of the Ploughshares Fund. “They had never seen anything like that.” Killing the program, he said, was “the first programmatic impact of the new [zero nukes] policy. People have said they want to see more than words, this is the very first action.”“

I know this is a bit wonky, but this is what it boils down to: Obama said he wanted to move to a post nuclear military world. Many have said this before like Bush/Cheney II, but then started to fund new nukes like “Bunker Busters” through our Nuclear Regulatory system to hide it. Obama actually stops funding new nukes all together. This is actually quite huge.
