He proclaimed on Twitter: "Mission accomplished", echoing former President George W. Bush, whose use of the same phrase in 2003 to describe the USA invasion of Iraq was widely ridiculed as violence there dragged on for years.
"Any unilateral military action bypassing the Security Council runs contrary to the objective and principles of the United Nations charter and violates the principles of worldwide law and the basic norms governing global relations, and will further complicate the Syrian issue".
Here are statements from some Congressional Leaders regarding the United State's joining France and Great Britain in conducting these attacks.
The United States, France and Britain, Dunford said, "did not do any coordination" with the Russians on the strikes, nor did they were pre-notified by the US.
The site west of the city of Homs was an alleged underground chemical weapons storage facility, doubling as a command post. "During the congressional debate, I will assess whether additional military action would do more harm than good by setting off a chain of consequences that could involve American fighting men and women in another long-term Middle Eastern conflict".
Analysts suggested Assad's regime would respond to Trump's threats by protectively moving weapons and personnel away from likely targets. Footage and photographs after the raid showed destroyed concrete office blocks and Syrian soldiers picking their way through the rubble.
Speaking on the BBC on April 15, British Foreign Secretary Boris Johnson said that the strikes were about saying "enough is enough" over what he called the "barbaric" use of chemical weapons.
He said a combined operation had been launched with the forces of Britain and France, whose leaders have rallied behind Trump's call for a response to an alleged chemical attack on the town of Douma a week ago that rescuers and monitors say killed more than 40 people.
The Violations Documentation Centre, which records alleged violations of global law in Syria, said there were attacks at 4.30pm and 7.30pm.
"As we work in civilian pharmaceutical and chemical research, we did not expect that we would be hit", he said.
"The OPCW has proven in two reports that this building and the centre as a whole are empty and do not produce any chemical weapons".
"Just as it did with the war on ISIS, the USA has compartmentalized the (chemical weapons) issue and isolated it from the broader Syrian conflict". In 2017, the US launched missiles against Syria following reports of a sarin gas attack.
Haley has been one of the administration's sharpest critics of Russian Federation, particularly with regard to its relationship with Syria.
Sami Nader, head of the Levant Institute for Strategic Affairs in Beirut, said, "The sustainable involvement of the U.S.in partnership with France and the United Kingdom will be a counterweight to Russian Federation and Iran in Syria".
The UN Security Council on April 14 rejected an effort by Russian Federation, a key ally of Syria, to denounce it as an unjustified "aggression" against a sovereign state. He learned only Tuesday that he would be attending in Trump's place so the president could manage the US response to Syria.
The narrowly targeted pre-dawn military operation, which took aim at 3 alleged chemical weapons facilities, earned quick scorn from Russian Federation, but a push by Moscow for condemnation of the strikes at the Security Council fell far short. "Right now this is a one-time shot", he said. "They do point to miosis or constricted pupils, convulsions and disruptions to the central nervous system", she said.
He added that the Him Shinshar chemical-weapons bunker facility near Homs was targeted with seven missiles and was "successfully hit".
The Western airstrikes targeting suspected Syrian chemical weapons facilities might have rained down punishment from the sky, but they will not fundamentally degrade a war machine whose main bases, weaponry and personnel remain in place.
Nikki Haley said: "When our president draws a red line, our president enforces the red line".
