The only comment I have on the Rubio speech is that I don’t want to spend too much time on the Rubio speech.
Nothing is changing with regards to US policy. We don’t need to do a line-by-line analysis.

How does the saying go? — ‘watch what I do, not what I say’
US Secretary of State Rubio says US and Europe "belong together" as he strikes different tone to JD Vance's blast at Munich one year ago.

This was a really fun conference, w. great papers and presentations. And at a time when the news always seem bleak, it also provided some hope. Across a number of countries, the CRS/AEoI have had strong effects, decreasing offshore secrecy - showing what's possible with international cooperation
How effective are transparency innovations in curbing offshore tax evasion? We’re spending the next two days examining the latest evidence on illicit financial flows.

Over 20 financial institutions have pledged not to finance deep sea mining, but several of the same banks invest in companies preparing to mine the seabed for minerals. 🤔

Even under SCOTUS's dubious reasoning in Trump v. U.S., there is no scenario in which maneuvering billions of dollars to an offshore account to keep it out of reach from Congress and courts is an "official act." This is all criminal and impeachable.
Marco Rubio: "The oil proceeds are being deposited into an account that ultimately will become a US Treasury blocked account here in the US. We will say 'this is what this money can be spent on.' They will submit to us a budget request -- 'we want to use the money on these things.'"

The Spanish government’s policies largely look like what you would expect/want from a left-party government. And: “Goldman Sachs recently described Spain as ‘Europe's fastest-growing major economy’ […] outpac[ing] Germany, France and Italy since the post-pandemic recovery.” A model, if you will
