Not to mention the US acquisition of Puerto Rico!

One might add that Spanish was a language on about a third of what is now US territory before English was.
But I won't pretend to be surprised that the Idiot-in-Chief doesn't know what the Treaty of Guadalupe Hidalgo was.

Turns out that trying to explain what he means by DEI without admitting to his racism, misogyny, and homophobia is, um, hard for him.

A win for academic freedom.

Being a professor is a tough job because we have a lot of competing pressures, but remember that we have an obligation to govern ourselves.

Perhaps Thoreau's most powerful line from CIVIL DISOBEDIENCE: "Under a government which imprisons any unjustly, the true place for a just man is also a prison."

"Witness the present Mexican war, the work of comparatively a few individuals using the standing government as their tool; for, in the outset, the people would not have consented to this measure."

Arguably the US-Mexico War was even more unpopular, (although of course there was no polling at the time to give us concrete numbers as to public support). But consider that the US-Mexico War was greeted by anti-war petitions to Congress and Thoreau's classic text, CIVIL DISOBEDIENCE.

Nuclear experts undercut White House claims about Iran reactor at heart of case for war The Trump administration sent negotiators without nuclear expertise to lead talks on Iran’s enrichment program. Now, its public case for war centers on a facility that experts say cannot do what offic...

This is a technical story with stunning strategic implications. It is quite possible the US launched a massive war because Jared Kushner and Steve Witkoff lacked the technical expertise to even understand what the Iranians were offering in negotiations. Absolute idiocy.

Honestly, I am absolutely disgusted by academics suggesting that AI can do the reading and writing for you. At a certain point, what you're bragging about is fraud. And in a broader sense, what you're contributing to is the erosion of knowledge and the destruction of trust in academic publishing.

Trump Tells Latin American Leaders 'I'm Not Learning Your Damn Language' at International Summit President Donald Trump told Latin American leaders during his 'Shield of the Americas' summit that he doesn't plan on 'learning your damn language'

Spanish is also "our damn language": the US is home to the second-largest Spanish speaking population in the world (exceeded only by Mexico).

Not a Cormac McCarthy fan at all, but his passage is infinitely better than the derivative AI version.

Justin Fox Deposition (Part 3) in MLA-ACLS-AHA Lawsuit about the NEH
Justin Fox Deposition (Part 3) in MLA-ACLS-AHA Lawsuit about the NEH YouTube video by ModernLanguageAssoc

It's stunning how ignorant the DOGE bros were who were sent into agencies. Justin Fox cannot even articulate in his own words what his "present understanding of DEI" is: he can't even formulate a coherent sentence about it. I wouldn't hire him for basic tech support. #NEH

To clarify this: the context is college sports. Trump is saying that Russia helping Iran target Americans in a war is less important than the pay structure for athletes. (1/3)

Wow -- as first spotted by @BadFoxGraphics on X, Fox & Friends this morning used *old footage of a previous dignified transfer* to mislead their audience about the fact that Trump wore a baseball cap during the one yesterday

When DOGE Unleashed ChatGPT on the Humanities

Funding of these projects was awarded after a rigorous vetting process involving layers of scholarship. An NEH award is difficult to get, and @nehgov.bsky.social funding was less than 0.01% of federal budget. The "DOGE" boys, with no expertise and AI, destroyed the integrity of a 50-year-old agency.

Seeing ppl circulate projects whose NEH grants were canceled by DOGE reaffirms my argument about AI as a permission structure. Some grants were canceled w/o a β€œno” from the generated summary. DOGE had a mandate to slash humanities funding & AI gave them the veneer of a rationale for their actions.
