"We Did Nothing; Why the truth doesn't always come out when the U.N. goes in" - by Linda Polman
Here's a review of this book:

A friend of mine from the United Kingdom gave me this book to read last summer. She had been in Bosnia during the war with a citizens commission that was investigating the genocide that was going on at the time. It is her contention that the world must through some agency be empowered to intervene on behalf of humanity when outrages are being carried out (which they almost always are).
This book is written by a journalist who was in Somalia, Haiti, and Rwanda while they were in their deepest trouble. Her description of just a day in Rwanda will tear at your heart strings, and with any luck, you'll be ready to send your own check to the U.N. The book is very anecdotal, an easy read.
