US, British and French forces pounded Syria with more than 100 missiles early on Saturday in response to a poison gas attack that killed dozens of people last week, in the biggest intervention by Western powers against Syrian President Bashar al-Assad.
Director of the Joint Staff Lt. Gen. Kenneth McKenzie confirmed that Syrian President Bashar al-Assad still maintains "residual" capacity.
Trump had tweeted a similar statement last Sunday, saying that Russian Federation and Iran are responsible for backing Assad's regime.
As pictures of the bombing raids aftermath continue to emerge, Mr Trump said he "could not have had a better result".
"This collective action sends a clear message that the global community will not stand by and tolerate the use of chemical weapons", May said at a press conference, calling the military action "right and legal".
May added: "The Syrian Regime has a history of using chemical weapons against its own people in the most cruel and abhorrent way".
Syrian TV showed police waving Syrian flags apparently on the edge of the town just east of Damascus, and said the "terrorist presence" in Douma will end "in a few hours".

Those deficits will quickly build, doubling the government's main pool of debt over the next decade. Annual deficit spending will top $1 trillion by 2020.
Huge blasts were reported around Damascus early on Saturday, moments after the US, France, and Britain announced they were striking Syria's chemical weapons capabilities. "I salute the men and women of our Armed Forces who conducted this mission bravely and skilfully with our British and French allies".
Washington described its targets as a centre near Damascus for the research, development, 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.
The US then endorsed a Russian backed plan to remove chemical stocks from Syria and more than 1,300 tons of chemical agents were removed.
French President Emmanuel Macron and British PM Theresa May also confirmed that United Kingdom and France have joined hands with the USA in carrying out an attack on Syria.
But Vassily Nebenzia, Russia's ambassador to the United Nations, accused Western powers on Friday of using the alleged attack as a pretense to oust Assad and to check Russia's power, telling the United Nations security council that Russia would consider such a strike a "breach of worldwide law".
McKenzie said that the Pentagon assessed that over 40 surface-to-air missiles were employed by the Syrian government. Tehran also slammed the US's decision of launching air strikes in Syria.
Damascus, with key allies Russian Federation and Iran, have lambasted reports of the suspected gas attack as bogus.
The senior administration official said, "What you've seen tonight is not the end of the USA response".
