what does anne's diary tell about the progress of war and its effect on eight people ?

I think there are a lot of themes at play here. Certainly resilience, survival, and hope are traits shared by all the characters in the annex. Though Anne claims to despise politics, she cannot help but become caught up in the war. It is the war, after all, that is responsible for her family's living situation. The adults in the annex, by contrast, speak constantly about the war and their prospects after the war. Throughout the diary, the phrase "after the war..." hangs over the book, an unfulfilled wish of every annex resident. Towards the end of the diary, when the Allies begin making great progress against Germany, Anne's diary entries document every battle and every landing--a great mirror into her excitement about the prospect of leaving the annex for good.
