Please share a source that's not a CIA funded NGO or think tank.

"Please share a source" is an incredibly dumb retort in the realm of geopolitics.

"Please share a source that the allied powers are going to invade the beaches of Normandy". You can't, because people are working incredibly hard to keep that secret.

So you don't have any? ok.

Yes, there is very little public sourcing for what hostile powers plan to do in a geopolitical struggle. That's how it goes.

It is perfectly reasonable to infer what might happen based on past actions by the specific powers, and on world history. Attempting to gain geopolitical influence through propaganda is nothing new.

So we should "just trust" the same people who said that Saddam had WMDs?

No. But these are two very different fact patterns.

In one case it was "we have specific evidence of something that should cause us to go to war".

In this case it is "we can infer that a hostile foreign power will use a straightforward conduit to push propaganda to our populace if we come into conflict".

It's defense, not offense.

What can China do to our social networks that is materially different than what American tech companies are already doing today?

Maybe I'm being naive because I don't use TikTok, but all the partisan misinformation I see is being spread by either Americans on American social networks or maybe Russian disinformation bots operating on American social networks.

Given enough time - subvert your government. Take control of your country :))

Just say what you came to say, instead of asking these questions.

The only reason anything America ever does is to make sure others don't ever have the power to stand up to stop the shenanigans it plans for the world. i.e. so called Rules Based Order.
