I'm still shocked when people ask, "aren't all archives online now" ... no, far from it. Most of the best stuff is buried away in dusty files in the most unexpected places.

Yes, going back to the Cold War, aligning political and industrial goals in the context of joint defense projects proved to be v. difficult both between the US and Europe and within Europe.

Great discussion about subsea cable security at IISS in Singapore. The office view is pretty great too.

Beautiful view this morning of the Singapore Strait

I’ve thoroughly enjoyed exploring the Cold War-era subsea cable collections at the National Archives of Singapore.

Many thanks to Will James for hosting me at RSIS (Nanyang Technological University) in Singapore to give a talk on U.S. Spacepower and alliance politics from the Cold War to today.

Many thanks to Australia National University for hosting @fiona-cunningham.bsky.social and me in Canberra last week to discuss strategic deterrence from the Cold War to today!

Found this in the Australian National Archives: message from Sep 1914 that describes when German forces landed on Fanning Island to cut the British Pacific Cable.

This is the declassified effectiveness criteria, from the late '80s, for SDI. The JCS intended for it to be able to destroy 50% of an SS-18 attack and 30% of all other Soviet missile systems. I discuss this in chapter six of my book. BL: 100% was never the *official* goal.

Satellite tracking station on Ascension Island. Since the 1960s, the facility has supported US missile tests and satellite launches from Cape Canaveral.

I thoroughly enjoyed driving out to the Deep Space Communications Complex outside Canberra, Australia that is used to track and communicates w/ NASA spacecraft. The site played a critical role in the Apollo program. Quite a sight seeing sheep grazing near the gigantic antennas.

Early cybersecurity: this declassified 1982 memo discusses potential Soviet exploitation of commercially provided computer database services

To contend with accidental undersea cable breaks and possible sabotage, the United States and allies must expand their repair infrastructure, writes @aaronbateman.bsky.social. "To keep the world’s data flowing, countries need to quickly fix broken undersea cables." ⬇️

Declassified memo from Gus Weiss on computer exports to China in the early 1980s

Stretching more than 1 million km, submarine cables serve as the global information highway. To keep data flowing in case of breaks, the U.S. and its allies must expand their repair infrastructure, explains @aaronbateman.bsky.social in a piece for @thebulletin.org. thebulletin.org/2025/07/to-k...

My latest in the Bulletin: Subsea cables that carry over 95% of global telecommunications are inextricably linked with US national security, but they are vulnerable. I use lessons from the Cold War to recommend strategies for making them more resilient. thebulletin.org/2025/07/to-k...

That time the US briefed senior Vatican officials on SDI as a measure to get the pope on the administration’s side. This declassified memo is the prelude to the first of multiple
