This picture has since been republished with Yannick Trottier's (the photographer's) permission in Ian Morris's "War, What Is It Good For?" in 2014. The attribution in the book incorrectly suggests that copyright is still held by Yannick Trottier. The correct license is given below.--Ytrottier (talk) 02:45, 5 May 2014 (UTC)
