I'd start buy giving an overview of what you are going to debate and what conclusion you are hoping to come to as a result of the debate.
Whether it is a debate or an article or an essay writing needs a good start- a creative one- and also a relevant one to the topic too. So if you are going to write a debate start it creatively. For example:1) write few verses about the topic its better to write it yourself but if you cannot quote from any poet.2) Start the topic in a humorous manner so that people do not get bore and want to listen more of it.3) A quote from a well known writer if the debate has to be serious.4) Some funny real life experience can also be shared before you formally start your debate.
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.
