Nice post @sauravrungta. I've been following this story for while now and, as you say, these videos were originally “leaked” via the New York Times in late 2017. However, the DoD has officially released them now and they are making the rounds on the MSM.
Whether UFOs are man-made, of other origin, or a mix of both (my current conclusion), it's likely that this release is part of an effort to distract people from what's really going on right now and to control the disclosure narrative.
Have you checked out the work of Steven Greer and Richard Dolan? They have good analysis on what might be going on. 🛸👍
