Members of the U.N. Security Council, worried about nuclear proliferation, have signed a new agreement to end the spread of nukes. Unfortunately, their deal’s not worth the paper it’s written on.

News in recent weeks on the nuclear proliferation front has been alarming, to say the least…

• Brazil’s vice president, Jose Alencar, asserting on Saturday that his country needs to develop a nuclear weapon in order to be taken seriously in the world.

• Venezuela’s strongman, Hugo Chavez, seeking help from both Russia and Iran to develop Venezuela’s nuclear know-how and, possibly, to build a bomb.

• India testing new, improved nuclear missiles in a bid to deter potential aggression from its nuclear foe, Pakistan.

• A.Q. Khan, the black market nuclear proliferator released from house arrest earlier this year, admitting in a recently released letter from 2003 to having sold nuclear secrets to China, North Korea, Iran and Libya, according to the London Times. And a recent Congressional Research Service report noting that Khan has been contacted by al-Qaida.

• Iran, just days before meeting with the National Security Council, testing new Shahab-3 and Sajjil-2 long-range missiles that bring Tel Aviv, Moscow, Athens and Italy “within striking distance,” Reuters says. Meanwhile, the U.S. has disclosed a second high-level nuclear processing site in Iran, as the mullahs begin using newer, more efficient centrifuges in their nuclear program.

• China celebrating its 60th year as a Communist nation with a parade of 108 nuclear missile systems, possibly including its Julang-2 submarine-mounted missile, with a range of 5,000 miles, and the CSS-X-10, its solid fuel intercontinental ballistic missile…

Not only is the world’s nuclear arsenal growing, but once a rogue nation gets a nuclear weapon — which now seems only a matter of time — we’ll face a changed world.  Suppose, for instance, Venezuela gets a nuke. How long will it take for the deranged dictator Chavez to use one, or to blackmail a democratic non-nuclear neighbor like Colombia or Chile?

Or the United States?

Obama, meanwhile, is lowering America’s defenses. He hopes to fend off America’s foes by speaking to them.
