For three weeks in 2009, Jeremy Deller and a handful of collaborators hauled a burned-up hunk of steel across the United States. This rusted carcass – a car destroyed in a Baghdad marketplace bombing in 2007 – transformed a vast swath of Middle America into a space for discussion about a war in which Washington long ago lost interest. It Is What It Is showcases transcripts of the group’s discussions, photographs from the obscure or eccentric locales where they occurred, and any number of other mementos from the group’s travels.
