The Listening Post begins with those disturbing images from Syria, the aftermath of that chemical weapons attack, that led to the US missile strike. The video went to air, showing the dead or dying victims, many of them children - and 50 hours later American missiles were hitting their targets.

The US strike came 77 days into Donald Trump's presidency, two and a half months marked by unprecedented hostility between the US media and a new administration. But nothing changes the narrative quite like pictures of a few Tomahawk missiles being launched into the night sky.

And the tone shifted.

Journalists praised Trump's decisiveness, his morality, and the might of the US military. He was described as something he'd seldom been accused of - being 'presidential.'

There are plenty of media angles in this story: from the haunting images of victims of chemical weapons, the impact the pictures are said to have had on Trump, to the video supplied by the Pentagon from those warships that is now driving the story.
