Technically, yes; because sarcasm involves saying something which isn't true. Usually it's said in such a way that everyone knows that you're not being truthful; but it's not always obvious to everyone. Virtually everyone understands sarcasm, but they may not recognize every usage of it.
And it's also possible to lie but then when you get caught try to claim that you were only being sarcastic.
Only if you are really trying hard to conceal your sarcasm!
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.
