"The United States is currently undergoing a “once in a generation” nuclear modernization program that will cost nearly $2 trillion over its lifetime and, ironically, take multiple generations to complete due to delays."
Excited to announce that my @ucs.org colleague and @scovillepf.bsky.social fellow Sean Manning has his first piece on the UCS blog. He provides a critical analysis of rising military spending & the expanding influence of the military-industrial complex. Take a look: blog.ucs.org/sean-manning...
The Exploding Scope of the Military-Industrial Complex
Members of both major political parties have begun to question ballooning defense expenditures, which have almost tripled since the 1990s.

Yesterday, Rep. @joeneguse.bsky.social joined us via Zoom at #AGU25 to reject the Trump admin’s proposal to dismantle the Ntl. Center for Atmospheric Research (NCAR), one of the US’ leading weather & climate research institutions.

“The research done at NCAR is an investment by every single tax-paying citizen in the United States, and it benefits all of us,” said UCS's @marc-alessi.bsky.social. “We are able to predict the weather days in advance, giving warning for hurricanes, extreme precipitation events, and droughts.”
We're all at risk if Trump dismantles this legendary lab
Breaking up the National Center for Atmospheric Research would be a "genuinely shocking self-inflicted wound."

I gave a more accurate comparison here: “We would need to deploy more than 24,700 Iron Dome batteries to defend the 3.7 million square miles of the continental United States. At $100 million per battery, that would be approximately $2,470,000,000,000.” www.defenseone.com/ideas/2024/0...
Can Donald Trump really build an Iron Dome over America?
In a word, no. The president-turned-candidate is still selling the same old missile-defense snake oil.

Climate litigation brought some big moments in 2025. Courts stepped in where political systems faltered as judges restored funding, protected rights, and kept the door open for climate accountability. UCS's Delta Merner recaps some of the biggest climate wins of the year:

A retired general argued that the fool's Golden Dome is feasible using an image stating the US system would defend an area 16 times larger than Iron Dome does for Israel. As the map shows, the US is in fact over 450 times larger. Expect more of this type of analysis from Golden Dome supporters.

A reminder that he has virtually unrestricted nuclear launch authority as you watch all the unhinged, racist, and sexist shit that Trump is spewing.

For your consideration:
In World War II, about 70 million people were killed in a conflict lasting 6 years.
Today, the US could kill 70 million people in less than an hour using roughly one-tenth of its deployed nuclear arsenal.
It would have another 1400 nuclear weapons.

At some point @nuclearanthro.bsky.social you asked if the FY26 Stockpile Stewardship and Management Plan was late and might be expected soon. I went back & looked & Team Biden didn't release their first SSMP until March 2022, so they were late too. Here's the page:
