🧵 Trump foreign-policy is overwhelmingly reality-television optics. More sound and fury than shock and awe. It doesn't put in the work. The deals it negotiates? Mostly vaporware. It announces "☮️ in our time" based on ceasefires. I'd bet good 💰 that 🇻🇪 will not be a vassal state for all that long.

you don't need to add caveats agreeing that the head of state abducted is a bad guy before opposing abduction of a head of state by military force. If the rule was any head of government is fair game then the entire world would be a series of decapitation strikes and show trials in foreign courts.

Cosmos-Politanism: Transhumanist Visions of Global Order from the First World War to the Digital Age
Cosmos-Politanism: Transhumanist Visions of Global Order from the First World War to the Digital Age By Duncan Bell, University of Cambridge and Apolline Taillandier, Newnham College Inspired by developments in artificial intelligence, space engineering, and genetics, discussion of post-human visions of the future is now widespread, especially in the tech world. This reflective essay analyses various ideological configurations of “transhumanism,” a body of thought centred on the pursuit of radical human improvement through technoscientific intervention.
