• International Approval Shapes Public Perceptions of Drone Warfare

    Drones that carry weapons are increasingly employed as counterterrorism tools, but nations use and constrain strikes differently. France, for example, submits its strikes to the U.N. for approval; the U.S. typically does not. This difference matters when it comes to public support and perceptions of legitimacy.

  • DHS S&T Awards $259M to Counter-Unmanned Aircraft System Threats

    Germantown, Maryland-based Amentum has been awarded a five-year contract with a maximum value of $260 million by DHS S&T to develop and deploy emerging capabilities and prototypes for countering unmanned systems threats (C-UST).

  • Many Factors Influenced the Severity of Burns from Oregon's 2020 Megafires

    In early September 2020, severe winds, high heat, and prolonged drought conditions led to the explosive growth of wildfires along the western slopes of the Cascades Mountains in the Pacific Northwest. New research confirms that extreme winds over the Labor Day holiday were the primary driver of the destructive force of the fires yet demonstrates how forest vegetation structure (e.g., canopy height, the age of trees, etc.) and topography played a significant role in burn severity patterns.

  • Russia’s War in Ukraine: China’s Lessons

    China is learning from Russia’s troubled war in Ukraine to improve its battle strategies and prepare for economic sanctions if Beijing ever attacks self-ruled Taiwan. Experts say that China may also be looking harder at peaceful solutions for Taiwan, they say.

  • Disrupting Deterrence: The Effects of Technologies on Strategic Deterrence

    What are the implications of eight specific emerging technologies for both the effectiveness of U.S. deterrent policies and the stability of deterrence relationships?

  • Geoelectrical Methods in Search for Hidden Graves

    Rather than digging to identify unmarked mass grave sites or evidence to locate missing persons, cutting-edge technologies are helping law enforcement agents, forensic scientists and historians uncover attempts to hide victims.

  • Drenching Rains Pose Greater Threat to Fire-Damaged Areas in West

    Areas in the western U.S. scarred by wildfires now face even more dangers: drenching rains. These rains inundate the burnt areas, causing significant destruction, including debris flows, mudslides, and flash floods, because the denuded landscape cannot easily contain the drenching moisture.

  • The Strategic Choices Ukrainian, Russian Military Leaders Are Facing in the Donbas

    With the war in Ukraine in its seventh week and Moscow pressing its campaign more forcefully in the east and south, fighting could become more brutal as the guerrilla-style tactics Ukrainians used around Kyiv to repel Russian forces shift to a more conventional battle of military might. Lawrence Freedman, emeritus professor of war studies at King’s College London and author of The Future Of War, explains what this new stage of the conflict will look like.

  • The Battle for Donbas Will Be Protracted and Bloody

    For eight years, Russia and Ukraine have fought in the Donbas region, with Russian regular army elements supplementing separatist units. Now, after defeat in Kyiv, Russian forces are redeploying there to take on Ukraine’s best and most experienced units. The battles to come will resemble more the maneuver battles of the second world war than those fought around the cities of Kyiv, Mariupol and Sumy in the six weeks the war has raged so far. Nonetheless, the Russians are unlikely to prevail.

  • Google Fights Dragnet Warrant for Users’ Search Histories Overseas, but It Is Continuing to Give Data to Police in the U.S.

    Google is fighting back against a Brazilian court order to turn over data on all users who searched for specific terms, including the name of a well-known elected official and a busy downtown thoroughfare. Google should be applauded for challenging this digital dragnet search in Brazil, but the company must also stand up for the rights of its users against similar searches in the U.S. and elsewhere.

  • Another Problem for Russia in Ukraine: Effective Satellites Are Few and Far Between

    The Russian forces have faced many problems in Ukraine. A big item on the list of problems: satellites — there are too few of them, and too few with high-quality capabilities. According to experts and open-source information, Russia has long been saddled with a small and inadequate fleet of communications and surveillance satellites that in many cases rely on either outdated technology or imported parts that are now harder to come by due to Western sanctions.

  • Why the War in Ukraine Poses a Greater Nuclear Risk than the Cuban Missile Crisis

    There has been a considerable debate of the risk of nuclear escalation growing from the current Russian war in Ukraine. Some dismiss the concern about a possible Russian first use of nuclear weapons in Ukraine, but Lawrence Korb and Stephen Cimbala write that “[d]ismissing Putin’s nuclear saber rattling as a ploy to manipulate NATO and world opinion, however, would be a mistake. The likelihood of a deliberate or miscalculated escalation to nuclear first use is now as great, or greater, than it was during the fateful Cuban missile crisis of 1962.”

  • Entering Dangerous, Uncharted Waters: Iran’s 60% Highly Enriched Uranium

    As soon as mid-to-late April, Iran is expected to reach a new dangerous, destabilizing threshold, having enough highly enriched uranium (HEU) — about 40-42 kilograms (kg) of 60 percent enriched uranium (uranium mass) — to fashion a nuclear explosive.

  • Risks of a Dirty Bomb Attack Are Increasing

    In a new factsheet, the GAO says that the risks of a dirty bomb attack are increasing and the consequences could be devastating.

  • New Wildfire Detection System Receives Funding Boost

    The high intensity of the recent fire seasons in Oregon, coupled with the increasing wildfire risk this year as approximately three-quarters of the state is now in severe drought conditions, has highlighted how critical a new project, aiming to help with the early detection and monitoring of wildfires, is — both for firefighters and the general public.
