Forum:Outer Heaven?

Why is there A Swastika on the Outer Heaven Flag? I know that it used to mean good luck and was used before the Nazis took it but why would Hideo Kojima put it on a flag that Big Boss used? And if it was Big Boss' dream of ending abuse and exploitation of soldiers why did he use the Swastika? Is there a reason that i am not understanding because it doesn't make much sense to me.
