You do know that China simply steals or buys its way into a lot of technological progress, right?
and You do know that the USA simply stole or bought its way into a lot of technological progress too, right?
The parent claimed this is propaganda because it violates the principle that LEO altitude has no air for an air-breathing scramjet engine. But he's apparently trolling since the engine could be a serial combination of the different ones in a neat way; or it could have a separate rocket engine; or whatever, but nobody claimed its scramjet mode operate all the way to LEO.
Read TFA again. Nobody claimed it would go to LEO on scramjet
Chinese combined cycle engines like this blueprint would be paired with a scramjet (presumably via changing the ramjet) and a separate rocket motor to create a hypersonic space plane.
the Chinese see that as attempts from western colonizers to control, and humiliate China... Again, they don't realize we've moved on from colonization, and we're happy to be partners with them
And how do you know if that (to control or colonize) is not true? Do you work for the CIA?
Look around the world, the only real competitor to the US (and its puppet Western allies) is China. Just think about that if one day Chinese Yuan succeeds becoming a real competitor to the USD and that most other countries are willing to trade everything include petroleum in RMB and accumulate RMBs as reserved, we would be much more like Greece. And all our allies would become theirs.
That's why we care about their political suppression so much. If China is irrelevant, we would care them as much as we care about Zimbabwe. If we truly want them to be our partner, we would care as much as we care about those same issues in Saudi Arabia or now Vietnam. (We did, back in 1970s, but not now. See below.)
it's foolish for China to try to force Taiwan to join them (the Taiwanese don't trust China
Yeah, Taiwan should forget that we betrayed them back in the 1970s when we made China, along with Afgan and bin Laden, allies to fight the Soviets, and start trusting us again, so they can be our puppet too.
But what if it were actually the Chinese who made First Contact? What if the aliens end up being forced to work in factories, making shoes up to 18 hours a day?
Then the American government will cite it as another evidence in its annual Human Right Report and promptly deport those aliens to Mexico.
