That first one was almost interesting, though I have forgotten what I wanted to say about it since I watched it several days ago before it was deleted and didn't bother posting.
The second is just an artistic video and has nothing to do with government conspiracies. I thought it was very well-done, though it did get boring at times, and I couldn't quite get the storyline. The music was cool though!
I just had to lol at the third. Again, nothing to do with conspiracies. Just a bunch of VG graphics thrown together in a horrible story. I absolutely LOVED the map at 4:18. As if the U.S. nuking itself would drive axis powers away, and after totally destroying itself it could somehow muster up enough soldiers to win the war. And who would develop oval-shaped explosions anyway? I thought the whole thing just didn't make sense.
Overall, I'm not quite sure how this thread connects with government conspiracies, and am not certain what your statement "Lovely world we live in" has to do with fictional, futuristic, artistic creations.
