You should not do anything in DllMain which depends on another DLL. You violate that at least three times: printf and std::cout depend on the CRT (which in turn depends on Win32 DLLs) and CreateThread depends on Kernel32.DLL.
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.
