Unfortunate. After the fact images are important to verify damage, incidents, claims. Time delay seems arbitrary. Why 24 days? Why not 7 days, or 1 day.

Trump’s war against Iran is causing oil prices to rise, creating higher gas prices at home for his voters, stock market to slump to the dismay of his rich friends, and Russia to make more oil money to fund its war machine in Ukraine. If only we could have known? 🙄

Yes, turns out the ICBM test launch today only carried two RVs. The Mk12A can carry up to three. Normally they fly 1 or 3 warheads. Here’s the more detailed USAFGSC description: www.afgsc.af.mil/News/Article...

The USAF test-launched a Minuteman III ICBM from Vandenberg into the Pacific. The missile carried three unarmed Mk12A reentry vehicles for the 335-kiloton W78 warhead. The MIRV test comes as US is considering increasing deployed warheads. www.vandenberg.spaceforce.mil/News/Article...

Not shedding any tears for brutal Iranian leadership. But talk about textbook distraction campaign: No imminent Iranian threat against US at level requiring attack, Trump’s ratings slump, Republicans facing tough midterm election, so let’s get some strongman action.

Apart from the role of conventional strike in general, I find it hard to believe that two nuclear powers that have spent their entire nuclear careers on planning how to overcome Russian missile defenses suddenly won’t be able to.

Marco reports another Minuteman III ICBM test launch planned for early next month.

USAF is trying to replace Minuteman with Sentinel but is over budget and behind schedule. Mil said Minuteman couldn’t be life-extended but now has to operate it for another 15 years. fas.org/publication/...

Trump aides struggle with how to spend $500 billion more on military Some senior officials resisted the decision to approve the major military spending increase, sources say.

While the Trump regime slashed government agencies and foreign aid and fired tens of thousands of government employees, it vastly increased spending on the military. Now it’s struggling with how to actually spend it all. www.washingtonpost.com/business/202...

How to Respond to China's Alleged Nuclear Test There are no good or easy answers

I've started a new substack on nuclear issues while between positions (new gig starts on March 2). Here is my first piece on how to digest allegations that China conducted a nuclear test in 2020. Thoughts from the #nuclear and policy community welcome as always.

Among the great mysteries in this universe is why any religious person can possibly have any confidence in Trump’s ethics. Is there any of the Ten Commandments he hasn’t violated?
