UnderSecT DiNanno: "China has used decoupling method to decrease the effectiveness of seismic monitoring to hide their activities from the world. China conducted one such yield producing nuclear tests on June 22 of 2020"

Good take- one way you can guess that the concept of "grand strategy" is somewhat flimsy is that the question of "how do we know if a grand strategy is good or not" tends to lead to rhetorical contortions that would make fun pasta shapes.

Scoop: U.S. and Russia agree to observe New START nuclear pact after expiration New START is the last major guardrail constraining the nuclear arsenals of the two countries that together hold some 85% of the world's warheads.

Axios reports a draft agreement has been reached in Abu Dhabi between Witkoff/Kushner and Russian officials on sticking to New START limits after treaty expiration. Still needs to be approved by Trump, but seems likely. Deus ex machina www.axios.com/2026/02/05/n...

This makes the case for a successor agreement stronger, as more transparency would be beneficial about these systems.

Good thread. I’d add that while the loss of transparency via inspections is significant, that has not been in effect for years at this point and would be less important anyway as new Russian systems are developed that fall outside the treaty limits.

The basic problem with the United States' call for Europe to lead on conventional forces while it takes care of nuclear deterrence.

Trump suggests the U.S. will resume testing nuclear weapons President Donald Trump appeared to suggest the U.S. will resume testing nuclear weapons for the first time in three decades, saying it would be on an "equal basis" with Russia and China.

No idea if this will mean actual testing of weapons or of old (or new) delivery systems, based on the qualifier of matching Russia/China. Likely they don't know yet (or perhaps don't know the difference). www.npr.org/2025/10/30/g...

The USG needs to improve public comms about cyber espionage - and refrain from conflating it with offensive cyber operations. Further, it should think through how OCOs might impact crisis stability with China - particularly as China might seek to reveal such capabilities as tensions mount. /FIN

One complicating factor in all this is that these hacks are playing out in public, which raises the bar for US government responses. It's difficult to clearly tell the public what the difference between "Salt" and "Volt" are.

A scramble at Cisco exposes uncomfortable truths about U.S. cyber defense When WikiLeaks founder Julian Assange disclosed earlier this month that his anti-secrecy group had obtained CIA tools for hacking into technology products made by U.S. companies, security engineers at Cisco Systems <CSCO.O> swung into action.

But the United States has (allegedly) conducted similar compromises of telecoms for intelligence purposes. See for instance: www.reuters.com/article/tech...

Like many US policymakers, Neuberger conflates China's Salt Typhoon (telecom espionage) with Volt Typhoon (pre-positioning in critical infrastructure). She suggests that compromises of telecoms could have been used to disrupt civilian and mil comms during a conflict.

China Is Winning the Cyberwar America needs a new strategy of deterrence.

Fmr DNSA Anne Neuberger argues that, in response to the Chinese cyber threat, the US needs to establish a "new cyber-deterrence policy". This side-steps an important question: what should be the limits of adversary cyber espionage against the US?

It’s night in Iran now - once the sun rises and if weather is clear, satellite imagery may give clues about the impact but info will be limited. Follow-on strikes could be based on subsequent intel. Likely next desired target would be fissile material through Iran but that is a difficult quarry.

Following a loud public outcry about job cuts at the National Parks Service β€” and a relentless media campaign from outdoors enthusiasts across the country β€” it looks like the Trump administration has blinked.

I lost my job. USDA Forest Service.


My probation was up next week.


I did everything right. I took a GS-7 role with a master’s degree just to get my foot in the door. I spent years doing seasonal fieldwork for low pay, working in remote places, gaining experience, and building skills, just for a chance at a permanent position. I was about to be a GS-9. I wrote NEPA reports. I conducted field surveys. I worked fire support. I dedicated myself to this work because I believed in it.


Public lands don’t manage themselves. The wildlife, watersheds, and forests we protect don’t just stay protected without people on the ground making it happen. My coworkers and I took on that responsibility, often in places most people never think about but that matter more than they know.


And now? Just like that, I’m out.


Edit: I’ve consistently supported progressive policies and have voted Democrat in every national and local election since I was 18. I do appreciate folks asking, I have some coworker having a serious 'leopards ate my face' moment right now.

This comment on r/fednews really stood out to me. Trump and Musk want people to think they're firing do-nothing "bureaucrats," but they're really getting rid of people dedicated to serving this country and keeping it operational. I hope these stories get told.

For instance, fielding interceptors in space raises new escalation risks - and means that the US would still need to rely on deterrence to protect its missile defenses!

In my view, the EO adopts a strategy of "throw everything at the missile and hope something sticks" without considering some of the strategic trade-offs in these forms of missile defense.
