Donald Trump has committed the most profound, harmful and unnecessary economic error in the modern era. Almost everything he said—on history, economics and the technicalities of trade—was utterly deluded econ.st/3YbbFjq

“The overwhelming claim has been that dark energy is no longer consistent with a cosmological constant […] However, this conclusion — despite how widely reported it’s been — is completely premature”

Could someone just unplug the US and then plug it in again?

Francesco the taxi driver was listening to a discussion of European security (or lack thereof) on the radio. Literally as we passed the Roman Forum, he addressed me with real sorrow: people have forgotten history. My Italian is poor but the context helped

Trump was right! When you hire people for their race or gender, you don’t get the best and brightest

Another line crossed in the descent into authoritarianism. Government strong-arming a law firm into compliance. (gift link) www.nytimes.com/2025/03/20/u...

A correct decision, too late. Irredeemably tainted by the stain of succumbing to a bigoted authoritarian regime

It’s important to map out our universe! But dynamical dark energy remains wildly implausible. It’s a fanciful notion, requires fine tuning worse than a pencil on its tip, and yet more tuning for the sole purpose of hiding itself from observers for so long. I call it a unicorn in a duck suit here:

Today Donald Trump called Canada the "nastiest" nation. Good grief

“There isn’t a mirror on the planet big enough for the Democrats and the left to look into, to see all the ways that they elected Trump. No mirror is big enough for them. But now this is what we have.” www.newyorker.com/news/the-new...

Highly authoritarian behaviour to deport lawful residents for saying & doing things that don’t violate the law. The same powers could be abused to target a wide range of politically dissenting voices with a chilling effect on free speech.

The Trump regime is doing a trial run at disappearing people, and they are starting with those least likely to cause a pushback. If you accede merely because you despise the first victim, you are legitimizing the authoritarian. Push back now or forever hold your peace.

I doubt that Khalil would go out of his way to defend liberal democracy, if his side were calling the shots. He is the mouthpiece of a movement that selectively condemns Israel’s war crimes but not the Hamas atrocities that led to that war. I am not on his side.

This is when it counts. An easy scapegoat was arrested without (so far) any criminal charge—ironically, under the pretense of fighting antisemitism. A president who embraced white nationalists is bragging about this outrageous abuse of power.

CDU/CSU &SPD have just proposed a sea change in German fiscal policy: - defence spending above 1% of GDP exempt from debt brake - 10-year €500bn special fund for infrastructure - looser debt rules for states - further debt-brake reform in new Bundestag

There is a scenario (probability: 30%?) in which Merz just happens to be a counter-intuitively good fit for the moment. A peculiar combination of curmudgeonly old-West German conservatism, Atlanticist realism, and European romanticism that somehow blasts Europe's caution away.

Donald Trump is aggressively undermining America’s significance on the world stage, except as a pariah state and sad servant of Vladimir Putin and the Russian Federation. Any of us in America who believe in democracy must look to leadership in Europe.

Russia's response to Trump's tantrum says it all really:

White House is the new Kremlin
