China to sustain top-down, debt-fueled investment in major projects and security capacities, ex-official says

Pekingnology • 33 implied HN points • 10 Aug 25
🌍 World Politics Security
  1. China plans to keep investing heavily in important projects and security measures for the next five years. This means that the government will continue to fund big projects to help boost the economy.

You Can't Get There From Here.

Trying to Understand the World • 9 implied HN points • 26 Nov 25
🌍 World Politics Security
  1. The word “war” with Russia is vague and dangerous: without clear, concrete assumptions about what a conflict would actually look like, any military planning is almost meaningless.
  2. Geography, distances and logistics make large-scale conventional campaigning across Europe impractical today, so conflicts would be decided largely by missiles, drones and how well states can police air and sea frontiers.
  3. What’s needed is a realistic NATO political-military doctrine and practical plans for limited scenarios (frontier policing, Baltic/Finland, Black Sea), not symbolic troop gestures that could be destroyed or escalate the situation.

Making Sense of The Après-Ukraine.

Trying to Understand the World • 7 implied HN points • 11 Dec 25
🌍 World Politics Security
  1. You can’t easily draw universal lessons from Ukraine because the war’s context is unique, political, and many lessons won’t be practical or agreed on.
  2. Logistics, ammunition and sheer numbers often matter more than individual platforms: large stocks, resupply and integrated command let forces fight for years, and massed missiles or drones can overwhelm defenses.
  3. Drones and new technologies are important but conditional — defenses will adapt, the West will adopt them slowly and unevenly, and these tools will create unexpected civilian, criminal, and military uses.
