I think the keyword you're looking for is RewriteCond. It's pretty similar to what you ended up with.
You might be able to use RewriteCond to check if an actual file exists... at least, I use this for websites when I want things like CSS, Javascripts, and images to be accessible (without the request being redirected.).
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.
