He has continued to rail against the war while in office, and his supposed aversion to becoming entangled in unwinnable foreign conflicts led him to declare, just a few days ago, that he wanted to pull all USA troops out of Syria. The US 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". Officials said this did not include giving Russian advance notice of where or when allied airstrikes would happen.
Washington described its targets as a center near Damascus for the research, production and testing of chemical and biological weapons, a chemical weapons storage site near the city of Homs, and another site near Homs that stored chemical weapons equipment and housed a command post.
"We, of course, know our work in Syria is not done", USA ambassador to the United Nations Nikki Haley said on "Fox News Sunday".
Russian Federation had promised to respond to any attack on its ally and said on Saturday that Syrian air defenses had intercepted 71 of the 105 missiles fired.
Several U.S. officials, speaking on condition of anonymity, said it was not a priority for the administration to push out Assad, who has survived with massive aid from Iran and Russian Federation.
British Foreign Secretary (Minister) Boris Johnson defended Prime Minister Theresa May's decision to take part in the attack, saying it was to deter further use of chemical weapons.
"We've attacked the heart of the Syrian chemical weapons program", said Lt. Gen. Kenneth F. McKenzie Jr.
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".
In an announcement, Trump said the attack was underway in retaliation for Syrian President Bashar al-Assad's alleged use of chemical weapons on rebel-held areas of the country. Before sunrise on Saturday, loud explosions jolted Damascus and the sky turned orange as Syrian air defense units fired surface-to-air missiles in response to three waves of military strikes. "I suspect, however they'll think long and hard about it".
The U.S. -led operation gained broad Western assist.
Disputing the Russian army's competition that Syrian air protection items downed 71 allied missiles, McKenzie mentioned no USA or allies missiles had been stopped. He said Syria's air defences were ineffective and that numerous more than 40 surface-to-air missiles fired by the Syrians were launched after the allied attack was over. He mentioned the US knew of no civilians killed by allied missiles. The World Health Organization said 70 were killed in the attack, with 43 dying from chemical exposure.
But he appeared to conflict that message when he said on Saturday that Western allies were prepared to "sustain this response" if Assad does not stop using prohibited chemical weapons. "No other group" could have carried out that attack, May said, adding that the allies' use of force was "right and legal".
