It took three years and two federal lawsuits for The Washington Post to pry loose more than 2,000 pages of interview notes with generals, ambassadors, diplomats and other insiders who offered firsthand accounts of the mistakes that have prolonged the war in Afghanistan.

The Post has made all of those interviews, plus hundreds of confidential memos by former defense secretary Donald H. Rumsfeld public and easily accessible so that Americans can see for themselves what has been done in their name.

From the more than 400 interviews, The Post has selected — and annotated — 25 that are essential reading and put key revelations from The Afghanistan Papers into stark relief.
