For years I've tracked billionaire excess. Each year I show students a chart that blows their minds. This year I had to redraw it for a trillionaire: Elon Musk, $1.32T. Depressing that we're here. Silver lining: couldn't have happened to a less deserving person, proof that wealth ≠ merit.

V-Dem v.16 is now released, w. updated scores for 2025. Most countries remain stable from 2024, but some clear improvements (on diff’t democracy indices), incl. S. Korea, Sri Lanka & Mauritius. Largest declines came, by far, in the US. This figure shows 10-yr changes on the Liberal Dem. index.

As the Hormuz crisis becomes a food security crisis, the @wfp.org is going into 2026 in a massive funding hole due to aid retrenchment by the US and many European donors facing the prospect of rearmament. The geopolitics driving the crisis are also leaving the cupboard bare for crisis response.

AI presents a fundamental threat to our ability to use polls to assess public opinion. Bad actors who are able to infiltrate panels can flip close election polls for less than the cost of a Starbucks coffee. Models will also infer and confirm hypotheses in experiments. Current quality checks fail

Rubio’s position seems to be: - We get to say who is a terrorist. Our decision is final. It can’t be challenged. Just trust us. - Once we decide you are a terrorist, we can immediately deport you. No judges. - After we deport you, we can make you rot in a foreign prison. No criminal charges needed.

Europe urgently needs to ramp up defense spending. But it must do so without risking a repeat of the euro crisis. @lucasguttenberg.bsky.social and I think the Commission’s current plan to use the flexibility built in the EU’s fiscal rules will not achieve this. Short thread: tinyurl.com/327u4ph6

Europe intends to rapidly and strongly increase its defense spending. It should do so without risking Europe’s fiscal sustainability and financial stability at a time of great danger.

Here is United States law regarding the President's attempts to close our development assistance agency in secret over the weekend. It is illegal. No ambiguity. Americans decide with their actions, today, if the US is a country of laws or—something else. —> crsreports.congress.gov/product/pdf/...
Can the President Abolish, Move, or Consolidate USAID?
Because Congress established USAID as an independent establishment (defined in 5 U.S.C. 104) within
the executive branch, the President does not have the authority to abolish it; congressional authorization
would be required to abolish, move, or consolidate USAID.
The Secretary of State established USAID as directed by Executive Order 10973, signed on November 3,
1961. The agency was meant to implement components of the Foreign Assistance Act of 1961 (FAA, P.L.
87-195), enacted on September 4, 1961.
Section 1413 of the Foreign Affairs Reform and Restructuring Act of 1998, Division G of P.L. 105-277,
established USAID as an “independent establishment” outside of the State Department (22 U.S.C. 6563).
In that act, Congress provided the President with temporary authority to reorganize the agency (22 U.S.C.
6601). President Clinton retained the status of USAID as an independent entity, and the authority to
reorganize expired in 1999. Congress has not granted the President further authority to abolish, move, or
consolidate USAID since.
