depends whether the war affects day to day life( ot death) or whether it is in some remote part of the world. If we think WW2 ( and from Great Britains perspective) there was the total mobilisation for the war effort, conscription, shortages, daily danger, restrictions of movement, propaganda and not knowing if you'd live to see your family the next day
( both my parents lived in the south east and endured the bombing as chidren and therefore I have heard their sometimes horrific stories often enough)- having relatives in the services ( both my grandfathers who I never knew, served for pretty much the whole war). If the war is far away, unless it actually impacts upon you, it tends to be a case of "out of site out of mind" and the effects are minimal. War brings out the best and worst in people-mostly is a pointless affair and is usually conducted by people who have little say over the war in the first place. Like has been said, debate it in your mind and I am sure you will start to cook and you will breeze through.
