On Aug 2020, a US spy satellite moved close to a Chinese satellite, attempting to shadow it closely. It was caught by the Chinese and they maneuvered it to get away from the US satellite. This seems to constitute ill or malign intent. Why would you go and bother the property of another person? What is the intent behind this move? Trust goes both ways, and it takes effort from both parties to build trust. This kind of…

What could possibly be gained moving a satellite closer to another? Threatening to crash into it?

Satellites have maneuvering thrusters with a very limited supply of fuel that will last just long enough for the designed mission-life of the satellite. Approaching the satellite will cause an unplanned maneuvering burn that effectively shortens the life of the satellite.

For military satellites, proximity avoidance is fully autonomous. Therefore, you can design a satellite to chase other satellites to fuel exhaustion. I’ve been told this is an actual thing.

China is culturally an ancient agrarian society focused more on defending farmland than conquering nations. This is not really comparable to the U.S. which is an ideology-based nation that inherited European imperialism traits. China is not interested in controlling or imposing beliefs in the same way it's rivals are so we shouldn't interpret their actions with the same lens.

Your response is some empty trite paragraph that doesn’t even make sense. “Don’t worry, it’s all fine”

This is currently a very active area of so-called grey-zone[0] warfare. It goes beyond the US, which is better prepared for this than most. Some European governments recently started investing heavily in their own satellite warfare capabilities as a response to increasingly aggressive and diverse activities targeting their assets as well.

The lack of public awareness of gray zone warfare is truly astounding.

Why not? China and Russia are ramping up on military presence, maneuvers, and armament. Our top businesses are constantly under attack by nation state actors. I've witnessed a few attacks directly. I'd be willing to bet that there will be some action taken in Ukraine and Taiwan within the decade, possibly simultaneously.

I feel like the best way to prevent a Taiwan situation is to give them nukes. China would never invade if it meant losing their 10 largest cities. And when they throw a fit just say "but China, you already had nukes. Which part of China they are in is no concern of ours."

Japan, South Korea and Taiwan are all considered latent nuclear powers; they each operate numerous nuclear reactors and likely have the material and expertise on hand to create nuclear weapons in a matter of months (if they ever chose to.)

A Chinese hegemony world will be void of virtue signalling, moralizing and ideologization (esp in tech). Something that much preferable.

Yeah only just the complete top down control over the people of the world.

Us is imperfect and now we want an autocratic cabal to rule us with surveillance etc. What a joke.

The state of accepting something as honest or deserving of trust even though there is some doubt.

huh. that's basically the opposite of what I'd think of it as - on the American side of things, I read that as "shake them and see what falls out", i.e. see what they're hiding. I'm also not sure how to search for that kind of phrase though. "a good shake" / "give them a good shake" doesn't seem to find anything relevant in my google. Anyone know of effective ways to search for culturally-idiomatic phrases?

Everything done in the Chinese society is virtue signaling, moralizing, and ideologization. If you don't align with the party you will be pruned or re-educated. In this respect, every single statement is designed to signal alignment with the government, advance the party's chosen morals, and advocating for the party's ideology. This is one of the few times on HN I've actually seen someone post something that is not only 100% incorrect but 100% opposite of the truth.

Wouldn't a PRC embargo of the US hurt the PRC nearly as much as the US?

More. Exports to the US are a much greater % of Chinese GDP, than Chinese imports are of US GDP.

The US Navy could block all Chinese exports and imports by sea around the world, not only those between China and America. This is why China's "Belt and Road Initiative" (aka the 'New Silk Road') is so important to China. It's meant to decrease China's reliance on shipping for international trade, by opening up land routes across Eurasia.

Regardless of the article, space superiority is the new air superiority in that if you don't have it, you only ever have permission from whomever does.

Over space scale distances, the only meaningful sovereignty is the cryptographic integrity of your networks, which, as it turns out, can have 20min or greater RTT latency, so you also need a high degree of autonomy. There's also the small matter of the entire substrates of those networks being produced by fabs and on equipment controlled by a rival superpower. Post quantum algorithms and key distribution are going to literally define sovereignty in less than 30 years, and we haven't landed on one for standardization yet.

I get that a lot of americans want to forfeit their governments role in the world, but I'd invite them to consider the alternatives. What bothers me is that we've seen supersonic missiles from both China and Russia in the last couple of months, and officially the multi trillion dollar US military is mystified by them, while some random guy on hackaday just built a supersonic trebuchet for two hundred dollars. Someone should call him and tell him his country needs him, because its military is too busy navel gazing to do its one job.
