• Trump’s Threats Lead to Reflections in EU Over Nuclear Weapons

    Trump’s latest threats that he will take the U.S. out of NATO have gotten EU politicians and military experts talking about a European nuclear deterrence without Washington. Others are warning of a risky, hasty debate, and seek to downplay chances of a major stateside shake-up. Some suggest that France “Europeanize” its nuclear capabilities.

  • Attributing Biological Weapons Use

    Why is attribution of BW use important? During a biological incident, including BW use, what evidence might provide valuable information to facilitate attribution? What is the state of the science for determining the origin of a biological incident, including BW use? What capabilities does DoD possess or could it develop to facilitate attribution of BW use?

  • Gunfire, Screams, Carnage: As Mass Shootings Proliferate, Training Gets More Realistic

    First responders and law enforcement agents have for decades used simulations to train for mass casualty events such as shootings or natural disasters, especially after the Columbine school shooting in 1999. But in recent years, as mass shootings have become increasingly common in the United States, the simulations have become more and more realistic. Now, law enforcement and medical workers experience the sights, smells and sounds of gun violence to prepare for tragedy.

  • Maritime Power Shapes the World Order – and Is Undergoing a Sea Change

    Western global leadership was the result of centuries of sea mastery. Controlling the global ocean enables the projection of military power all over the world, as well as securing the free flow of goods at sea. The prosperity and security of trading nations strongly depend on the stability of the global maritime supply chain and thus on freedom of navigation. But now Western maritime superiority is being challenged by other rising powers and by insurgent groups.

  • The Iran Threat Geiger Counter: Reaching Extreme Danger

    The Iran Threat Geiger Counter from the Institute for Science and International Security measures on a regular basis Iran’s hostile actions and intentions toward the United States and U.S. allies, and its capability to turn these hostile intentions into action through the potential or actual construction of nuclear weapons. As with the radiation levels measured by a Geiger counter, any level above zero represents a degree of danger. Since May 2023, the date of the last edition of the Counter, the threat posed by Iran’s nuclear program has increased dramatically.

  • U.S.-North Korea Arms Control Talks or Denuclearization? Analysts Are Divided

    As Pyongyang continues to bolster its nuclear and missile programs while refusing to engage with Washington, analysts are divided on whether the U.S. should continue pursuing denuclearization or consider possible arms control options.

  • U.S. Raids in Iraq and Syria: How Retaliatory Airstrikes Affect Network of Iran-Backed Militias

    Iran’s “forward defense” strategy – focused on addressing threats externally before they become ones within its borders – would suggest that Iran will continue to support proxies through weaponry, funding and tactical knowledge to reduce the influence and legitimacy of the U.S. and its allies in the region. This underscores the delicate balance required in responding to Iranian-backed aggression – aiming to safeguard U.S. interests while preventing an escalation into a wider regional confrontation.

  • Mexico’s Lawsuit Against U.S. Gunmakers Has Cleared a Big Hurdle

    A federal law protects American gun manufacturers against most lawsuits, but an appeals court has allowed Mexico’s case to move forward. The Mexican government accusing America’s largest gunmakers of aiding and abetting the trafficking of weapons across the border.

  • Police Departments Are Turning to AI to Sift Through Millions of Hours of Unreviewed Body-Cam Footage

    Body camera video equivalent to 25 million copies of “Barbie” is collected but rarely reviewed. Some cities are looking to new technology to examine this stockpile of footage to identify problematic officers and patterns of behavior.

  • Directed Energy: The Focus on Laser Weapons Intensifies

    There a growing interest in directed energy weapons, once considered in the realm of science fiction. How to separate the considerable hype about these futuristic-sounding technologies from their more-nuanced impacts on the real-world battlefields of today and tomorrow?

  • New Low-Tech Innovation for Emergency Squad Communication

    Researchers developed a web-based automated dialing solution enabling civil defense units to communicate with each other during emergencies without Internet service. This low-tech ability is critical for times when connectivity is down; for squads comprised of ultra-Orthodox (haredi) Jews, who often do not have smartphones; and for older first responders who may be less technologically savvy.

  • Advancing the U.S. Coast Guard's Global Impact

    The U.S. Coast Guard is in high demand globally, engaging with over 160 countries on every continent and in every ocean. The service could better meet its strategic goals through enhanced internal coordination and prioritization of its international affairs efforts, as well as increased resources.

  • A Non-Proliferation Solution: Using Antineutrinos to Surveil Nuclear Reactors

    Antineutrinos generated in nuclear fission can be measured to remotely monitor the operation of nuclear reactors and verify that they are not being used to produce nuclear weapons, scientists report. Thanks to a newly developed method, it is now possible to estimate a reactor’s operation status, fuel burnup, and fuel composition based entirely on its antineutrino emissions. This technique could contribute massively to nuclear non-proliferation efforts and, in turn, safer nuclear energy.

  • The Challenge of Cheap Drones: Finding an Even Cheaper Way to Destroy Them

    The sudden proliferation of inexpensive drones in Ukraine is a revolution in warfare. While they vary in size and capability, the  economics of defense are particularly stressed by the very cheapest ones, those adapted from civilian models or made with commercially available components.

  • Hydrogen Power Takes Drones to the Next Level

    Most drones run on electric batteries and can stay aloft no more than about 45 minutes when carrying just a few kilograms. HevenDrones has another solution.
