So Purps, what is your overall take on disclosure? (I just read your post on FB about the Vatican, the group that still thinks women are inferior beings.)
Here's my take just to get the discussion going: I think all the governments, the UN, and everyone else in high places, knows about ET, but they're all stalling while they jockey behind closed doors to see how they can personally benefit and get a leg up on the competition. This is how they approach everything else, why would this be different? The U.S. could be stalling while they put the final touches on "ET defense technology" while trying to hide their Mars program, the Vatican may see it as a new way to get converts (the scared and the damned, for instance.)
I'm also betting that when the general public is finally introduced to what the rest of us have known (literally) forever, some of them will still deny, deny, just like the people of Boston who cheered their martial law vacation because they didn't have to go to work while they sheltered in place.
