• Worries grow about safety of Pakistan's nuclear weapons facilities

    All the terror strikes in Pakistan in the recent past have been suicide attacks, but the attack on the Pakistan Army’s General Headquarters in Rawalpindi three days ago was more of a commando attack carried out by well-trained jihadists; experts worry that such military-style tactics could be used against Pakistani nuclear sites

  • Pentagon orders accelerated production of 15-ton bunker buster

    The Obama administration is inching toward a dialog with Iran over the latter’s nuclear weapons program, but at the same time it readies the means to destroy Iran’s capabilities should the dialog fail

  • Radioactive rabbit poo found at plutonium production site

    A clean-up survey at the Hanford site in Washington State, where military-grade plutonium was produced during the early years of the cold war, discovered radioactive jackrabbit droppings around the site; the rabbits burrowed in the area and discovered the tanks in which nuclear waste is stored; they liked the salty taste of the radioactive cesium and strontium salts, so they began drinking and licking them routinely

  • Missile defense system that might just work

    The Obama administration’s decision to scrap the Bush administration’s plan to place ballistic missile defense systems in Poland and the Czech Republic, and replace it with short-range defensive systems closer to Iran, makes sense; instead of making a political point to Russia, the U.S. might now have in place a defensive system that works

  • Revelations about Iran's facility raise questions about U.S. intelligence

    Both the 2003 “slam dunk” assertion about Iraq’s WMDs, and the 2007 NIE’s conclusion that Iran had “halted” its nuclear weapons work, were absurdities; we should worry about the fact that they came to the surface — and influenced policy

  • Fujitsu asks terrorists whether they would use its software for WMD

    Fujitsu runs a patching site for Sun Microsystems’ Solaris Unix variant; the company asks end-users to fill out a survey before downloading the latest patch, and the first question asks whether the customer would be using the patch to build WMD; even if you admit to building a nuclear bomb, Fujitsu allows you to download the patch; either Fujitsu targets really honest terrorists, or the company wants to use the information in its advertising (as in: “5% of our customers are terrorists who use our software to build weapons of mass destruction”)

  • Understanding nuclear ignition better

    The U.S. nuclear warheads are aging; researchers looking for new ways to figure out safe and reliable ways to estimate their longevity and to understand the physics of thermonuclear reactions in the absence of underground testing currently prohibited under law

  • Pentagon asks Congress for funds for 30,000 bunker-busting bombs

    Intensifying the preparations for an attack on Iran’s nuclear facilities, the Obama administration has asked Congress for funds to accelerate production of a 30,000-pound “ultra-large bunker-buster” bomb designed to destroy deeply buried installations

  • Pakistani jihadists attacked Pakistani nuclear sites three times since 2007

    When Pakistan was developing its nuclear weapons infrastructure in the 1970s and 1980s, its main concern was that India would overrun these nuclear weapons facilities in an armored offensive; Pakistan thus chose to locate much of its nuclear weapons infrastructure to the north and west of the country — but this decision means that most of Pakistan’s nuclear sites are close to or even within areas dominated by Pakistani Taliban militants and home to al-Qaeda

  • U.S. military speeds up preparation for attack on Iran's nuclear facilities

    The Obama administration’s six-month exploration of ways short of war to persuade Iran to halt its accelerated march to the bomb has, so far, yielded nothing; these efforts, however, have allowed Iran more time and space to build more centrifuges, enrich more uranium, launch a plutonium path to the bomb, and test more sophisticated missiles; the administration can take a hint, and it is now accelerating preparations for a military attack on Iran’s nuclear weapons facilities

  • Israel's now more likely to attack Iran's nuclear facilities

    The test of Arrow 2 — Israel’s defense against Iran’s ballistic missiles — was aborted three times; Hillary Clinton says the United States would extend a “nuclear umbrella” to Arab countries: these two events combine to increase Israel’s anxiety about Iran’s nuclear weapons, and make an Israeli attack on Iran’s nuclear facilities more likely

  • Republicans try to keep Yucca Mountain project alive

    The Obama administration has signaled its intention to bring the curtain down on the Yucca Mountain nuclear waste repository project, but Republicans have not given up on it

  • Chance of nuclear war is greater than we think

    Stanford engineer makes risk analysis, saying the risk of a child born today suffering an early death due to nuclear war is at least 10 percent

  • Cities need to prepare for a home-made nuke

    An explosion of ten kiloton nuclear bomb in a city would be disastrous; as catastrophic as such an attack would be, it would not level an entire city, and a timely response could save many lives

  • U.S. Army considers blimps as anti-missile defense

    The U.S. Army is testing blimps for detecting, tracking, and shooting down cruise missiles; the radar-equipped aerostats are tethered balloons resembling blimps
