Haley said the three U.S. goals for accomplishing its mission are making sure chemical weapons are not used in a way that could harm U.S. national interests, defeating the Islamic State group and having a good vantage point to watch what Iran is doing.

“We’re not going to leave until we know we’ve accomplished those things,” she said.

Haley said the joint military strike “put a heavy blow into their chemical weapons program, setting them back years” and reiterated that if Assad uses poison gas again, “the United States is locked and loaded.”

French President Emmanuel Macron said Sunday that France wants to launch a diplomatic initiative over Syria that would include Western powers, Russia and Turkey. Speaking on French television BFM and online site Mediapart, Macron stressed that the French diplomacy is able to talk with Iran, Russia and Turkey on one side and to the United States on the other side.

He said, “Ten days ago, President Trump wanted to withdraw from Syria. We convinced him to remain.”

The nighttime assault on Syria was carefully limited to minimize civilian casualties and avoid direct conflict with Russia, but confusion arose over the extent to which Washington warned Moscow in advance. The Pentagon said it gave no explicit warning. The U.S. ambassador in Moscow, John Huntsman, said in a video, “Before we took action, the United States communicated with” Russia to “reduce the danger of any Russian or civilian casualties.”

Russia has military forces, including air defenses, in several areas of Syria to support Assad in his long war against anti-government rebels.

Russia and Iran called the use of force by the United States and its French and British allies a “military crime” and “act of aggression.” The U.N. Security Council rejected a Russian resolution calling for condemnation of the “aggression” by the three Western allies.

Assad denies he has used chemical weapons, and the Trump administration has yet to present hard evidence of what it says precipitated the allied missiles attack: a chlorine gas attack on civilians in Douma on April 7. The U.S. says it suspects that sarin gas also was used.

“Good souls will not be humiliated,” Assad tweeted while hundreds of Syrians gathered in Damascus, the capital, where they flashed victory signs and waved flags in scenes of defiance after the early morning barrage.

The strikes “successfully hit every target,” said Dana W. White, the chief Pentagon spokeswoman. The military said there were three targets: the Barzah chemical weapons research and development site in the Damascus area, a chemical weapons storage facility near Homs and a chemical weapons “bunker” a few miles from the second target.

Although officials said the singular target was Assad’s chemical weapons capability, his air force, including helicopters he allegedly has used to drop chemical weapons on civilians, were spared. In a U.S. military action a year ago in response to a sarin gas attack, missiles took out nearly 20 percent of the Syrian air force, the Pentagon said.

The U.S.-led operation won broad Western support. The NATO alliance gave its full backing; NATO Secretary-General Jens Stoltenberg said the attack was about ensuring that chemical weapons cannot be used with impunity.

In his televised address from the White House on Friday, Trump said the U.S. was prepared to keep up the economic, diplomatic and military pressure on Assad until he ends a pattern of killing his own people with internationally banned chemical weapons.

That did not mean military strikes would continue. In fact, Gen. Joseph Dunford, chairman of the Joint Chiefs of Staff, said no additional attacks were planned.

Asked about Trump’s “Mission Accomplished” assertion, White said it pointed to the successful targeting of the three Syrian chemical weapons sites. What happens next, she said, is up to Assad and to his Russian and Iranian allies.
