Before there were screaming children at the US southern border, there was Iraq. This famous photograph is of Samar Hassan, then 5 years old in January 2005, whose parents had just been killed by US soldiers who treated their car as hostile when it approached a checkpoint. The photographer who took it, Chris Hondros, was killed years later during the Libyan war.
The New York Times did a great story in 2011 to find out what happened to Samar. Her circumstances were OK, but not great, and certainly no recovery from the disaster captured in the image.
If the trajectory of the country is that every so often, a child terrorized by its actions becomes the signature image, it's time to reflect on a fundamental problem.
