Can I play new Playstation games on old Playstation consoles? Why, or why not?

Depends on the games you want to play. If you have your heart set on playing Halo with your friends, the PS4 is a bad choice.

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.
