I personally don't believe in disclosure coming from a governmental side. The only thing that would really disclose for me, is by my own experience and eyes.
I'd like some sort of disclosure to come, but not from any terrestrial officials.
The only scenario I can see coming from governments around the globe, is something down the line:
"Yes, we can confirm that aliens exist and that 9/11 was a inside job!!!"
"if....you are a complete nutjob!!"
I see loads of mockery going on these days, thrown in the direction of so called conspiracy nuts and disclosure believers. They handpick the worst case scenarios, showcasing for the general public the most stupid and absurd theories that have come out and ridicule them as being just like all other theories. Heck, even Donald Duck & Co had a short story about cropcircles and all the "nutjobs" that show up for something that "has" to have a natural explanation. :S
