• Mountain collapsed in North Korea after most recent nuclear test

    As North Korea’s president pledges to “denuclearize” the Korean peninsula, scientists published the most detailed view yet of the site of the country’s latest and largest underground nuclear test on 3 September 2017. The new picture of how the explosion altered the mountain above the detonation highlights the importance of using satellite radar imaging, called SAR (synthetic aperture radar), in addition to seismic recordings to more precisely monitor the location and yield of nuclear tests in North Korea and around the world.

  • Earthquake science could have predicted North Korea’s nuclear climbdown

    Just days after North Korea announced it was suspending its testing program, scientists revealed that the country’s underground nuclear test site had partially collapsed. The collapse may have played a role in North Korea’s change in policy. If correct, and with the hindsight of this research, we might have speculated that the North Koreans would want to make such an offer of peace. This shows how scientific analysis normally reserved for studying natural earthquakes can be a powerful tool in deciphering political decisions and predicting future policy across the globe.

  • The past as prologue? Iran’s nuclear weapons project

    In a major coup, Israel’s intelligence operatives smuggled tens of thousands of documents from Iran’s nuclear weapons archive – the existence of which Iran had denied – which show the methodical steps Iran took between 199 and 2003 to build nuclear weapons. Two nuclear weapons experts say that the very existence of the archive is proof that Iran not only lied about its past nuclear weapons plans, but also about its future plans.

  • Assessing the Iran deal pullout

    Calling it a “great embarrassment” that fails to “halt Iran’s nuclear ambitions,” President Trump said Tuesday that he will pull out of the Joint Comprehensive Plan of Action (JCPOA), the Iran nuclear agreement that the previous administration negotiated to halt that nation’s progress toward atomic weapons. The national security, nuclear, and regional experts at Harvard Kennedy School’s Belfer Center for Science and International Affairs, who have been assessing the Iran nuclear situation for years, examined the president’s remarks and weighed in on the significance of Washington’s policy change and on what is likely to follow it.

  • As U.S. withdraws from Iran nuclear deal, experts consider fallout

    U.S. President Donald Trump’s decision to withdraw from the 2015 Iranian nuclear agreement reverberated throughout the Middle East, Europe, and elsewhere – all the more so because did not say what comes next in U.S. policy toward Iran, leaving a list of questions that experts are rushing to predict: Will Washington seek new negotiations with Tehran? Will Iran resume enriching uranium? Will Israel step up attacks on Iran’s proxies, such as Hezbollah in Lebanon, or militias in Syria? Will the U.S. European allies try to coax the Trump administration back to the negotiating table with Tehran? Will U.S. forces in Syria become more of a target for Iranian fighters?

  • Presidents often reverse U.S. foreign policy — how Trump handles setbacks is what matters most now

    President Trump’s decision to withdraw from the Iran nuclear deal is hardly Trump’s first foreign policy turnaround. But is Trump really such an outlier? As a scholar of American foreign policy, I know that many American presidents have reoriented international relations. Some of those policies succeeded. Many faced opposition. Ultimately, though, my research shows that what matters more to U.S. national security is how those presidents responded when their foreign policy shifts failed.

  • Former Israeli national security advisor: If Iran attacks Israel again, “there will be consequences”

    Following a weekend during which Israeli officials warned that Iran was preparing to use proxies to attack northern Israel in retaliation for an airstrike against an Iranian airbase in Syria, a former Israeli national security advisor asserted that for any Iranian attack “there will be consequences.”

  • Ahead of nuke deadline, Israeli company detects unusual activity at Iranian enrichment site

    An Israeli satellite company has published photographs of “unusual” activity at an Iranian enrichment facility, a week before President Donald Trump will make a decision whether or not to continue America’s participation in the 2015 nuclear deal.

  • IAEA saw no “credible evidence” Iran was working on nuclear weapon after 2009

    In December 2015, following a series of inspections, the IAEA issued a report saying that the agency had “no credible” evidence Iran was working on developing a nuclear “explosive device” after 2009 and that the UN’s nuclear watchdog considered the issue “closed.” The IAEA said today (1 May) that the agency stands by those conclusions. The IAEA’s statement ccame after Israeli Prime Minister Benjamin Netanyahu said on 30 April that Israel had documents that showed new “proof” of an Iranian nuclear-weapons plan that could be activated at any time.

  • Radiation detection device to help in detecting nuclear weapons, materials

    Researchers have developed a next-generation material for nuclear radiation detection that could provide a significantly less expensive alternative to the detectors now in commercial use. Specifically, the high-performance material is used in a device that can detect gamma rays, weak signals given off by nuclear materials, and can easily identify individual radioactive isotopes. Potential uses for the new device include more widespread detectors — including handheld — for nuclear weapons and materials as well as applications in biomedical imaging, astronomy and spectroscopy.

  • EU said to reject ballistic missile penalties on Iran

    Members of the European Union are balking at imposing sanctions on Iran for its ballistic missile program. EU members Spain, Italy and Austria rejected proposed penalties by the United Kingdom, France, and Germany, which would penalize Iran for its continued ballistic missile program and support for the Assad regime in Syria’s civil war. These penalties would include freezing assets as travel bans on 15 individuals, companies, and groups involved in these endeavors.

  • Remotely monitoring nuclear reactors

    A new U.S. Department of Energy project to develop the first detector able to remotely monitor nuclear reactors will also help physicists test the next generation of neutrino observatories. Nuclear reactions produce telltale antineutrinos – the antimatter counterpart of neutrinos. The new detectors will be designed to measure the energy of such antineutrinos and the direction from which they come, allowing monitoring of reactors from a distance of 25 kilometers to verify nonproliferation agreements.

  • Former IDF intel chief: Bombing of Syrian reactor shows Israel will act alone to survive

    Maj-Gen. (Ret.) Amos Yadlin, Israel’s chief of military intelligence in 2007 said in a press briefing that the Israeli Air Force’s destruction of a Syrian reactor shows that when Israel is faced with “a very serious threat” to its existence, “Israel is going to act, and act even if Israel has to act alone.”

  • Israel admits destroying Syrian reactor in move seen aimed at Iran

    The Israeli military has formally acknowledged for the first time its destruction of a suspected Syrian nuclear reactor in 2007, saying the air strike removed a major threat to Israel and was a “message” to others. Israel’s announcement on 21 March about Operation Out of the Box is widely seen as a veiled warning to arch-enemy Iran as it builds up its military presence in Syria. Syria, with North Korean help, secretly built the reactor in the desert near Deir al-Zor in north-east Syria, in violation of the 1970 Nuclear Nonproliferation Treaty (NPT). North Korea planned to use the facility for separating weapon-grade plutonium from spent uranium, a nuclear-weapon related activity prohibited by the 1994 U.S.-North Korea nuclear Framework Agreement.

  • Khamenei military adviser: West uses lizards to spy on Iran’s nuclear program

    Saying that their skins absorb “atomic waves,” a top military adviser to Iranian Supreme Leader Ayatollah Ali Khamenei charged that Western countries use “lizards, chameleons” to spy on Iran’s nuclear program. Hassan Firuzabadi, a former chief-of-staff for Iran’s army, said that the spy lizards were released in various places in Iran to find out where inside the Islamic republic of Iran we have uranium mines and where we are engaged in atomic activities.”
