The most propagandistic aspect of the US War on Terror has been, and remains, that its victims are rendered invisible and voiceless. They are almost never named by newspapers. They and their surviving family members are virtually never heard from on television.
The Bush and Obama DOJs have collaborated with federal judges to ensure that even those who everyone admits are completely innocent have no access to American courts and thus no means of having their stories heard or their rights vindicated. Radical secrecy theories and escalating attacks on whistleblowers push these victims further into the dark.
It is the ultimate tactic of Othering: concealing their humanity, enabling their dehumanization, by simply relegating them to nonexistence. As Ashleigh Banfield put it her 2003 speech denouncing US media coverage of the Iraq war just months before she was demoted and then fired by MSNBC: US media reports systematically exclude both the perspectives of "the other side" and the victims of American violence.
Media outlets in predominantly Muslim countries certainly report on their plight, but US media outlets simply do not, which is one major reason for the disparity in worldviews between the two populations. They know what the US does in their part of the world, but Americans are kept deliberately ignorant of it.
