Ummm im not sure how prepared depending on how it was delivered (like in a missile or aircraft or what) but I do know there are measures to counter them. For instance there are sites all over the country to shoot down missiles.

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.
