As a very generalized view, for decades after WW2, the US was seen by other nations as the top dog in terms of military power, technological development, and an example of how society could flourish by following a political system. While these ideas can be debated, there are at least some good examples like space travel, the internet and middle-class wealth, that concur with the argument. The idea of imminent disclosure however implies the US wouldn't be top dog anymore.
For this reason, I wonder if the theatrics associated with COVID and BLM are a way of desensitizing people to the idea that the US isn't 'top dog' anymore.....e.g. 'how could the most advanced nation on earth be most overwhelmed by a virus?' or 'how can there be so much divisiveness in the land of the free?' I'm not suggesting these are realistic questions or viewpoints, just trying to see the situation from the rest-of-the-world's viewpoint. Whatever faith there previously was in the US from people of other nations, as well as potentially people inside the US, by letting the responses to major events be what they have been so far, it leaves people deflated (possibly designed that way on purpose) --> A prime time to release a bombshell piece of information that relative to all the other world events currently going on is far less shocking and destabilizing?
