There’s been “no change” to the U.S. military stance in Syria beyond the missile strike in retaliation for the Assad government’s use of chemical weapons on its citizens, yet the action carries a message for other countries acting outside international norms, Secretary of State Rex Tillerson said.

The U.S. still hopes to shepherd a “political process that we believe the Syrian people will lawfully be able to decide the fate of Assad,” Tillerson said Sunday in reference to Syria’s president on ABC’s “This Week With George Stephanopoulos,” one of two appearances on political talk shows.

This week’s airstrike “was a message to Bashar al-Assad that your multiple violations of your agreements at the UN, your agreements under the chemical weapons charter back in 2013, that those would not go without a response in the future,” he said.
