Why do american history textbooks gloss over the recent past? What according to you, is the last date for history vs. curren events? (e.g. do events in 2000 count as history? or 1995? 1990?)

History needs some time for gaining perspective on the past events. I would say 25 years is a minimum to separate history from "current events".

Our history books are brand new and currently up to date, note that the series we just replaced was from the 1990's.
