Senior US admin official says Assad wouldn't have been toppled absent US support for Ukr & Israel. No "serious" outreach from Assad to USG. US urged Iraq to "stay out of it". And: "future here will be written by Syrians. We are not coming up with a blueprint from Washington" Asked if USG is in contact with HTS, the US official says: " it's safe to say there's contact with with all Syrian groups". Says HTS is a "broad kaleidoscope" and US has to be "smart" in dealing with it, "mindful and pragmatic about about the realities on the ground."

Punchy intro to CDS Xmas lecture at RUSI from @MTSavill: “last month's announcement of cuts… is emblematic of a dept. that is struggling to reconcile people and money with existing commitments at a very time when the threats that we face are growing in scale and complexity” Image Radakin warns North Korean deployments could become a larger flow: “This year's most extraordinary moment was the deployment of thousands of North Korean soldiers on the border of Ukraine and the possibility of tens of of thousands more to follow” as part of DPRK-Russia pact Image

An instructive podcast, published six days ago, with Pete Hegseth, Trump's nominee for the secretary of defence position. A few takeaways:
podcasts.apple.com/us/podcast/143… Hegseth: "I would probably talk a lot about the military industrial complex... the companies that influence the way we procure weapons and way we fight. Well, there's the veterans industrial complex too...allow the private market to provide for vets ... the VA hates that."

“JPMorgan Chase, a bank, has estimated that a tariff hike half the size of the one Mr Trump is advocating would knock a third to half a percentage point off gdp growth in its first year and increase inflation by 1.5-2 percentage points.” economist.com/briefing/2024/… “Mass deportations of the magnitude that Mr Trump has proposed are also unlikely to happen. The federal government simply would not have the capacity to hunt down and deport millions of people unless Mr Trump were to enlist the armed forces or deputise…law enforcement”

This is a very good discussion with @liscovich, providing a clear picture of what the drone war in Ukraine currently looks like (rather than how it looked a year ago). A few points that stood out to me: 1. We're on to the third generation of First Person View (FPV) drones. "The overall trend has been toward using larger [air]frames that can carry more payload [with] frequency shifting." Bigger antennae—30W v 2W—to strengthen signal and counter impact of Russian jamming.

I wrote this week on the latest skirmishing in the crypto wars. End-to-end encryption has conquered the world. Governments continue to push back in defence of lawful intercept. But the debate around technical solutions has changed little in years.
economist.com/international/… A few sources for this piece. In 2018 & 2021 a pair of GCHQ officials proposed various solutions for reconciling gov't interception with end-to-end encryption. The first piece proposed that govts could be added secretly to particular communications:

Kommersant reports from Kursk. General sense being chaos & abandonment by Moscow. “I want to understand where our state is at all? Where is the administration? I wish they could talk to us. We don't know anything at all… there's no one.” kommersant.ru/doc/6890223 “Why wasn't there a fucking evacuation? Everyone ran away as best they could - under fire, under kamikaze drones!

Struck by the fact that we can barely work out with confidence which Ukrainian brigades & what proportion of them are properly in in Kursk, let alone if anything is in reserve & what precisely is happening. OSINT can be absolutely magical, and sometimes incredibly limiting. And so beware wild evidence free speculation however enjoyable it feels. Image

🧵 While I am going through notes, there is also a good discussion here between @StaciePettyjohn & @NarangVipin, the US' Secretary of Defense for Space Policy (and an MIT professor). Some interesting bits on nuclear policy/strategy incl. NATO nuclear posture. Narang says scenario "flipped" from cold war, where NATO planned nuclear first use. "NATO is the conventionally superior [one]. And so the muscle memory we have from the Cold War is not actually not as applicable...the central challenge is how do we deter Ru first employment "
