In e-mail, sure. Here, I'll just say that they might've been close pals. My cousin calls them "The Three Amigos", if Panboukin was included in there.
In fact, if you watch "Tatahitori no Saisho Kesen" and read in-between the lines (or watch in-between the lines, whichever), you'll notice that they could pass as brothers (especially if you saw how Toma teased Panboukin and Bardock in the scene before Bardock was attacked). "The Three Amigos"... I think I like "The Three Stooges" better... more.
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.
