The Trump Assassination Attempt Has Historical Precedents — and Future Security Implications
Have we entered an era of political upheaval in America where political violence will become the backdrop for U.S. politics? Recent studies on attitudes toward political violence indicate that a small but not insignificant number of Americans support the idea of using violence to advance political ideas. While Trump is the victim of this heinous attack, it’s difficult to ignore how he has catalyzed extreme political polarization by repeatedly acting to demonize his opponents.

Hundreds of Tech Companies Want to Cash In on Homeland Security Funding. Here's Who They Are and What They're Selling.
Whenever concerns grow about the security along the U.S.-Mexico border and immigration, the U.S. government generate dollars — hundreds of millions of dollars — for tech conglomerates and start-ups.

Businesses Are Harvesting Our Biometric Data. The Public Needs Assurances on Security
Visual data capturing and analysis are particularly critical compared to non-visual data. That’s why its growing use by businesses raises so many concerns about privacy and consent. While the public remains unaware of the extent to which their visual data is being captured and utilized, their information will be vulnerable to misuse or exploitation.

Reports: DHS’ Parole Programs Allowed Inadmissible Violent Criminals to Enter, Stay in U.S.
A wave of violent crime has befallen Americans nationwide connected to parole programs created by Department of Homeland Security Secretary Alejandro Mayorkas, according to several reports. A pattern has emerged of single men illegally entering the U.S. who are considered inadmissible under federal law. Instead of being processed for removal, Border Patrol agents released them with a “notice to appear” before an immigration judge several years into the future.

To Guard Against Cyberattacks in Space, Researchers Ask ‘What If?’
If space systems such as GPS were hacked and knocked offline, much of the world would instantly be returned to the communications and navigation technologies of the 1950s. Yet space cybersecurity is largely invisible to the public at a time of heightened geopolitical tensions.

A Nuclear Sword of Damocles in Orbit
Russia is developing a nuclear-weapons-based anti-satellite (ASAT) capability, and the Western democracies must work together to prevent Moscow from deploying such a weapon. That will demand new and innovative thinking on space domain awareness and space control by the US and its allies. A continued drift forward through a strategy of hope that Russia will honor its obligations under space law even as the West is under direct threat from Moscow is a strategy for failure.

U.S.’s Terrorist Listing of European Far-Right Group Signals Fears of Rising Threat − Both Abroad and at Home
The rise of the radical far right in Europe poses a threat not only to the continent but also to Americans at home and abroad. But while the U.S. government tends to be quick to use sanctions against perceived bad actors across the globe, when it comes to the transnational threat that far-right violence poses, successive U.S. administrations have been more coy about using another critical and effective tool: terrorist designations.

The long view
Are We Ready for a ‘DeepSeek for Bioweapons’?
Anthropic’s Claude 4 is a warning sign: AI that can help build bioweapons is coming, and could be widely available soon. Steven Adler writes that we need to be prepared for the consequences: “like a freely downloadable ‘DeepSeek for bioweapons,’ available across the internet, loadable to the computer of any amateur scientist who wishes to cause mass harm. With Anthropic’s Claude Opus 4 having finally triggered this level of safety risk, the clock is now ticking.”
“The Federal Government Is Gone”: Under Trump, the Fight Against Extremist Violence Is Left Up to the States
As President Donald Trump guts the main federal office dedicated to preventing terrorism, states say they’re left to take the lead in spotlighting threats. Some state efforts are robust, others are fledgling, and yet other states are still formalizing strategies for addressing extremism. With the federal government largely retreating from focusing on extremist dangers, prevention advocates say the threat of violent extremism is likely to increase.
Luigi Mangione and the Making of a ‘Terrorist’
Discretion is crucial to the American tradition of criminal law, Jacob Ware and Ania Zolyniak write, noting that “lawmakers enact broader statutes to empower prosecutors to pursue justice while entrusting that they will stay within the confines of their authority and screen out the inevitable “absurd” cases that may arise.” Discretion is also vital to maintaining the legitimacy of the legal system. In the prosecution’s case against Luigi Mangione, they charge, “That discretion was abused.”
Autonomous Weapon Systems: No Human-in-the-Loop Required, and Other Myths Dispelled
“The United States has a strong policy on autonomy in weapon systems that simultaneously enables their development and deployment and ensures they could be used in an effective manner, meaning the systems work as intended, with the same minimal risk of accidents or errors that all weapon systems have,” Michael Horowitz writes.
Ukraine Drone Strikes on Russian Airbase Reveal Any Country Is Vulnerable to the Same Kind of Attack
Air defense systems are built on the assumption that threats come from above and from beyond national borders. But Ukraine’s coordinated drone strike on 1 June on five airbases deep inside Russian territory exposed what happens when states are attacked from below and from within. In low-level airspace, visibility drops, responsibility fragments, and detection tools lose their edge. Drones arrive unannounced, response times lag, coordination breaks.
Shots to the Dome—Why We Can’t Model US Missile Defense on Israel’s “Iron Dome”
Starting an arms race where the costs are stacked against you at a time when debt-to-GDP is approaching an all-time high seems reckless. All in all, the idea behind Golden Dome is still quite undercooked.
