For the first time since President Obama, in August 2011, articulated regime change in Damascus as a precondition for the cessation of the civil conflict that had been raging since April 2011, American government officials articulated that this was no longer the case.

“You pick and choose your battles,” the American Ambassador to the United Nations, Nikki Haley , told reporters on March 30, 2017. “And when we’re looking at this, it’s about changing up priorities and our priority is no longer to sit and focus on getting Assad out.”

Haley’s words were echoed by Secretary of State Rex Tillerson, who observed that same day, while on an official visit to Turkey,

This new policy direction lasted barely five days. Sometime in the early afternoon of April 4, 2017, troubling images and video clips began to be transmitted out of the Syrian province of Idlib by anti-government activists, including members of the so-called “White Helmets,” a volunteer rescue team whose work was captured in an eponymously-named Academy Award-winning documentary film. These images showed victims in various stages of symptomatic distress, including death, from what the activists said was exposure to chemical weapons dropped by the Syrian air force on the town of Khan Sheikhoun that very morning.

Images of these tragic deaths were immediately broadcast on American media outlets, with pundits decrying the horrific and heinous nature of the chemical attack, which was nearly unanimously attributed to the Syrian government, even though the only evidence provided was the imagery and testimony of the anti-Assad activists who, just days before, were decrying the shift in American policy regarding regime change in Syria. President Trump viewed these images, and was deeply troubled by what he saw, especially the depictions of dead and suffering children.

The images were used as exhibits in a passionate speech by Haley during a speech at the Security Council on April 5, 2017, where she confronted Russia and threatened unilateral American military action if the Council failed to respond to the alleged Syrian chemical attack.

“Yesterday morning, we awoke to pictures, to children foaming at the mouth, suffering convulsions, being carried in the arms of desperate parents,” Haley said, holding up two examples of the images provided by the anti-Assad activists. “We saw rows of lifeless bodies, some still in diapers…we cannot close our eyes to those pictures. We cannot close our minds of the responsibility to act.” If the Security Council refused to take action against the Syrian government, Haley said, then “there are times in the life of states that we are compelled to take our own action.”

In 2013, President Barack Obama was confronted with images of dead and injured civilians, including numerous small children, from Syria that were every bit as heartbreaking as the ones displayed by Ambassador Haley. His Secretary of State, John Kerry, had made an impassioned speech that all but called for military force against Syria. President Obama asked for, and received, a wide-range of military options from his national security team targeting the regime of President Assad; only the intervention of James Clapper, and the doubts that existed about the veracity of the intelligence linking the Ghouta chemical attack to the Syrian government, held Obama back from giving the green light for the bombing to begin.
