First, use the shortlink to your videos, not that long URL. The long link you posted is too long you could of just done this http://youtu.be/PVXBXKDwhDI just by clicking on the share button. Then the usual... Facebook, Twitter, G+, Yahoo Answers and so on.
Attach your video in the social site like as facebook, twitter etc.
Promoting a YouTube video takes work. Assuming your video is engaging enough to grab the attention of the viewer you can promote it through social media networks to try to gain varality. You can include it in your signature if you frequent forums (remember to not blatantly advertise it) Remember, word of mouth is always the best source or marketing.
Concentrate on those methods and see how it works for you. Good luck.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
