both what you expect and what you need
What does " This book has tried to explain that it is both what you expect and what you need." want to say?
What is war art? Is it a battlefield scene with churned-up blood-red earth, driving rain, smoking ruins, scattered corpses, and twisted metal detritus, all lit by white diagonal stripes of searchlights and the brilliant firework colours of exploding star shells? Is it the elegant monuments to victory and the spare, minimalist memorials to tragedy? Is it brutal in-your-face gratuitous violence? Is it a gentle, meditative wash of colour depicting no man’s land? This book has tried to explain that it is both what you expect and what you need. It is humankind portrayed at its best and at its worst. It is the record of civilization when life takes second place to death. It is the place where we reflect and remember.
