This feels like an op to me. The timing is uncanny. If this story develops, I predict some escalation of current conflicts with some advanced weaponry (chemical, biological, nuclear, energy, space-based, etc) and the alien story to be used as cover.
Alternatively, it’s a continuation of reactionary mobilization propaganda. Thought?
I can’t think of a better way to lead the conspiracy theorists by the mouth than have them defend DoD and ABC institutions they traditionally are skeptical of so they can cling to their fantasy.
