Something is definitely coming. It might be a disinformation campaign by the military-industrial complex or a revelation about some new discoveries in nature (including intelligent non-human life).
As an aside, it is doubtful whatever is being seen by the government is Russian/Chinese. If that were the case, our enemies would be behaving in ways that demonstrate their advanced superiority.
The Chinese can’t even replicate our stealth tech and they struggle to put vehicles into space. No way they have anti-gravitational tech. If It’s, Russian, they would’ve commercialized it long ago out of necessity.
