Question

1984 how is perpetual war no different than perpetual peace why does the inner pary alter the past

Answer 1

In Orwell's novel 1984, there is no  difference between perpetual war and perpetual peace.  For members of the inner party, perpetual war - which is everlasting by definition - does not allow for any changes in society.  The inner party changes or alters historical records of the past for a particular reason: people often make decisions about their present based upon incidents from the past.  By controlling the past, and the records and narratives related to it, the inner-party can control the way people thinking about the past, they can control how people think about the current day and the future.
