• New Law Targets Gun Trafficking to Mexico

    A new law that imposes harsher penalties on gun trafficking is giving U.S. prosecutors a powerful tool to combat the illicit flow of weapons from the United States to drug cartels in Mexico. The cartels use the weapons to protect their drug smuggling operations, fueling an overdose epidemic that is claiming the lives of tens of thousands of Americans.

  • Why Norms Matter More Than Ever for Space Deterrence and Defense

    As the uses of space grow in significance, so too has the question of how to keep space systems safe and secure. Robin Dickey writes that one of the potential answers to that question is to fill in gaps in norms of responsible behavior for space. “What may seem like a relatively niche topic actually supports a broad swath of U.S. strategic objectives and has become a central line of effort in protecting national security interests in the space domain,” he writes.

  • Boosting Supply Chains by Recovering Valuable Materials from Water

    Promoting national security and economic competitiveness will require America’s researchers to find new ways to obtain the materials that we need for many technologies. Traditional mining is fraught with challenges, while water, from the oceans to geothermal brines, is an underexplored resource for providing various materials.

  • We Aren't Helpless in the Face of Increasing Fires and Smoke

    Canada, Mexico, or the United States have published strategy documents that aim to rebalance fire’s place in our environment through methods such as prescribed fire. Even the most optimistic outlook on these efforts sees them as long-term solutions, though. Yes, a massive paradigm shift is necessary. But it’s also clear something needs to happen immediately, too. To protect ourselves, we can take steps that won’t distract from those long-term goals.

  • Research Agenda Prepares for the Future of Science and Technology

    DHS Science and Technology Directorate (S&T) works to prepare DHS for  the future of science and technology. The requires remaining aware (and ahead) of emerging science and technology threats along with harnessing the latest advancements in science and technology as cutting-edge solutions for homeland security operational challenges.

  • Iran Can Produce Enough Weapon-Grade Uranium for a Nuclear Weapon in 12 Days

    Iran can now break out and produce enough weapon-grade enriched uranium for a nuclear weapon in 12 days, using only three or four of its advanced centrifuge cascades and little more than one-third of its existing stock of 60 percent enriched uranium. This breakout could be difficult for the IAEA to detect promptly, if Iran took steps to delay inspectors’ access. Within four more weeks, Iran can produce enough weapon-grade uranium for four additional bombs.

  • States Invest in Nuclear Arsenals as Geopolitical Relations Deteriorate: SIPRI Yearbook

    The new edition of SIPRI’s annual yearbook finds that the number of operational nuclear weapons started to rise as countries’ long-term force modernization and expansion plans progressed. The size of China’s nuclear arsenal increased from 350 warheads in January 2022 to 410 in January 2023, and it is expected to keep growing. Depending on how it decides to structure its forces, China could potentially have at least as many intercontinental ballistic missiles (ICBMs) as either the USA or Russia by the turn of the decade.

  • Navigating South Korea’s Plan for Preemption

    South Korea has invested in systems designed to thwart a North Korean nuclear attack by preempting North Korean nuclear launch and attack missiles before they are launched – and also attacking the leadership and command and control nodes that support Pyongyang’s weapons of mass destruction. Clint Work writes that the South Korean approach is understandable, but that there is a catch: The constant talk of preemption “provides easy justification for North Korea to continually build more nuclear weapons. The result is that both sides may now be incentivized to adopt a “go-first” mentality during a crisis.”

  • The Microchip Industry Would Implode if China Invaded Taiwan, and It Would Affect Everyone

    Taiwan plays a critical role in the conflict between the US and China over computer chips. Taiwan has a huge share of the global semiconductor industry, but is also the focus of tensions between Beijing and Washington over its political status. If China invaded Taiwan, the global semiconductor industry would freeze, inflation would spiral further upwards, the post-COVID recovery would be reversed, and many of the tools we rely on would disappear from our shops for years.

  • How Texas’ Plan to Curb School Violence Was Knocked Down by a Pandemic and Little Oversight

    Threat assessment teams were created to prevent the next school shooting. However, confusion surrounds how these teams operate and what they even do with a child exhibiting threatening behavior.

  • Militia Members Indicted for Conspiracy to Murder Border Patrol Officers, Illegal Immigrants

    Two members of the self-styled 2nd American Militia who conspired to go “to war with border patrol” have been indicted two weeks ago by a federal grand jury on charges related to a conspiracy to murder Border Patrol officers and kill illegal immigrants crossing the border. The plot was thwarted by a shootout with FBI agents who arrested them.

  • Training for Nuclear Incidents and Preparing WMD Responses

    “Radiological material can end up in almost any location or any place and take on almost any shape and form,” an expert told participants a few weeks ago at the first Sandia Lab’s Weapons of Mass Destruction Counterterrorism and Incident Response Showcase. Preparing for nuclear incidents is not dealing with hypotheticals. “It is not practice. It is not an exercise. It is real life stuff,” he said.

  • American Extremists Serving as “Sources of Inspiration,” Says U.S. Counterterror Official

    There is a sense among senior U.S. counterterrorism officials that the actions of a handful of Americans are helping to drive the growth of racist and far-right extremist groups around the world. Specifically, these officials point to mass shootings and other high-profile attacks in the United States, which have helped to turn the perpetrators into martyrs for like-minded groups and individuals.

  • U.S. Former General: Russia Benefits from Dam Blast, Putin 'Likely' to Use Nuclear Weapons Rather Than Lose in Ukraine

    “I’m not the first to warn [Putin’s] threats [to use nuclear weapons] are serious. Many people say that his threats are serious, but then they quickly say, “However, they are not likely. I’m one of the few people who has said that these threats are not only serious but they’re likely to happen. That makes a threat urgent — something which others are not saying. If these threats are recognized as urgent, then the governments will do something about it; if they’re not urgent, or if they’re not likely, then the governments have many other things on their plate that they want to take care of that are urgent”: Brigadier General (Ret.) Kevin Ryan.

  • Teachers' Views on School Safety

    What are the most common safety concerns that teachers have in schools? How do teachers feel about arming teachers at school? Do they believe that arming teachers will make schools more or less safe? How do teachers’ opinions vary by individual and school-level characteristics? Would teachers choose to carry firearms at school if they were allowed? What impact do physical security measures (e.g., cameras, metal detectors) have on school climate? There is a consensus on many security measures, but stark division about arming teachers.
