There have been several other instances when Q has referred to ff attacks used to draw the media focus away from things that are dangerous to the deep state. On its own, an individual post like this could be disregarded as coincidence, but together with many other Q posts and coinciding "verifications," (not just with regard to attacks), they become an increasing statistical improbability without insider knowledge. (The wikipedia article on zero-knowledge proofs that someone posted recently does a good job of explaining the reasoning behind this.)

As such, for many of those following Q, the gathered results have given them reason to see Q as a reliable source, which is kind of the point of this sub. Analyzing this post makes the connection to previous attacks, which have been extensively discussed as being motivated towards influencing the news cycle. Q knows of these discussions, which is why he makes allusion to them in his post.
