4 cylinder have timing chain starting with model year 2003, prior to that it was all belts. V6 engines still have timing belts.
Change the belt and the tenseniors and idler pulley and a water pump. If one part fails it will ruin the others.
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.
