What Syrians need is not more bombs and missiles, but an end to the war, which has killed at least 400,000 people in seven years.
That was enough of a message for the USA authorities and the strike evidently achieved nothing.
The Pentagon repeated Saturday that the President has the authority under the Constitution to defend U.S. interests, but what happens next is up to the Assad regime and Russian Federation.
"Mission accomplished" is the same phrase former President George W. Bush infamously used in 2003, after the US -led invasion of Iraq.
The Syrian government and its allies have absorbed a US-led attack, and the targeted sites were evacuated days ago thanks to a warning from Russian Federation, a senior official in a regional alliance that backs Damascus said. "This time our allies and we have struck harder", Mattis said. "The strategy failed. It must be time for a new one".
France, the United States and Britain circulated a draft resolution to the U.N. Security Council late on Saturday that aims to establish a new independent inquiry into who is to responsible for chemical weapons attacks in Syria. "Insulting the president of Russian Federation is unacceptable and inadmissible".
Russian Foreign Minister Sergey Lavrov said last week his country had sent experts to the site and found "no trace" of chemical weapons use.
The U.S. has raised the prospect of more sanctions against Russian Federation. The legislation also called Putin out on human rights abuses.
The three allies have produced a draft United Nations resolution which also includes proposals for an independent investigation into alleged toxic gas attacks to identify perpetrators.
Syrian armed forces said in a statement, however, that the country's defense systems "intercepted most of the missiles, but some hit targets including the Research Center in Barzeh", a suburb of Damascus.
The "mission has not been accomplished", said Suzanne Akhras, president of the Syrian Community Network. Haley stressed the US was "not looking for war" and "not looking to kill people".
Haley rejected the premise posed by Fox News anchor Chris Wallace that the USA has condoned Assad's use of conventional weapons to kill rebels attacking his forces, just not chemical agents.
Piazza said further, limited airstrikes are possible in Syria. But their unified stance appeared to be shaken Sunday when Washington knocked back French President Emmanuel Macron's claim that Paris had convinced Trump to stay engaged in Syria "for the long-term".
The White House, mired in controversies, is not likely to pursue Assad too aggressively, Piazza said.
The Russian military said its air defenses at two bases in Syria tracked the incoming missiles but didn't engage them.
"Vladimir Putin, in particular, stressed that if such actions were committed in violation of the United Nations charter continue, then it will inevitably lead to chaos in global relations", the statement said.
She said the three U.S. goals for accomplishing its mission were making sure chemical weapons were not used in a way that could harm USA national interests, that the Islamic State group was defeated, and that there was a good vantage point to watch what Iran was doing.
