On March 30, 2017, Haley stated that the U.S. would no longer focus on forcing Syrian president Bashar al-Assad to leave power. This was a policy shift from former president Barack Obama's initial stance on Assad. On April 5, speaking to the U.N. Security Council a day after the Khan Shaykhun chemical attack, Haley said Russia, Assad, and Iran "have no interest in peace" and attacks similar to this would continue occurring should nothing be done in response. A day later, the U.S. launched 59 Tomahawk cruise missiles toward the Shayrat Air Base in Syria. Haley called the strike a "very measured step" and warned that the U.S. was prepared "to do more" despite wishing it would not be required. On April 12, after Russia blocked a draft resolution meant to condemn the Khan Shaykhun chemical attack, Haley criticized Russia, saying "We need to see Russia choose to side with the civilized world over an Assad government that brutally terrorizes its own people." June 28, while appearing before the United States House Committee on Foreign Affairs, Haley credited President Trump's warning to Syria with stopping another chemical attack: "I can tell you due to the president's actions, we did not see an incident."
