On Friday evening, President Donald Trump announced the launch of an international offensive against Syria’s chemical weapons infrastructure.

I ordered the United States armed forces to launch precision strikes on targets associated with the chemical weapon capabilities of Syrian dictator of Bashar al-Assad,” Trump said from the White House.

“The combined American, British and French response to these atrocities will integrate all instruments of our national power: military, economic and diplomatic,” Trump said. “We are prepared to sustain this response until the Syrian regime stops its use of prohibited chemical agents.”

The attack was prompted by the alleged use of chemical weapons against Syrian civilians in rebel controlled territory earlier this week, and the president made it clear that Friday’s strike was meant as reprisal.
