Yeah I am like 99% sure you can because I used to see people with portable DvD players all the time. However I have not traveled by plane for 2-3 years so they may have changed it, but am fairly certain they have not.
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.
