Just a few comments:

1. True. This dates from the 1960s (see Maj. Keyhoe's books).
2. You don't attempt to target anything when you have no knowledge of what the weapon effects would be. Starfish Prime was a test. Johnston Island was later maintained as an anti-satellite system. It would have had very limited maneuver capability.
3. Notoriety does not mean veracity.
4. For those who have been following the subject since the 1950s, the current interest is little more than a publicity fad. Serious books have been written on the subject in the 60s and later, but today nobody reads. It is watching the behavior of a public who never knew the history.
5. Insider claims are not worth the evidence they do not provide.
6. We do not even know if there is such a thing as "Project Looking Glass." Unfortunately, relying on a Q remark is also relying on the possibility of disinformation. There is no such thing as time travel or information from the future (neither the past nor the future exists; there is only the present).
7. Is "the topic of Roswell" classified at all? What topic would that be? The existence of the air force base (where they trained the B-29 pilots to drop the atom bomb)? Maybe that activity is still classified. The existence of a reconnaissance balloon program based there (shreds of which were identified as alien wreckage)? That was classified at the time and they needed a cover story.
8. A massive tease is a big disinformation event, right?

I doubt that anything will emerge soon. The most difficult thing to disclose is how little we know. (Saw an episode of "Strange Evidence" on TV last night. A Chilean Navy helicopter captured an image on a new infrared camera of a strange stationary IR source in the sky trailing a long plume. It turned out to be a distant 4-engine airliner traveling away, with engine nozzles and contrails in view. The helicopter crew misjudged the distance and the altitude.)
