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.
