"In a powerful show of allied unity, we deployed 105 weapons against three targets that will significantly impact the Syrian regime's ability to develop, deploy and use chemical weapons in the future", Gen. Kenneth McKenzie said on Saturday during a press briefing at the Pentagon. "There won't be anything, or anyone, even close!"
He backed Prime Minister Theresa May's decision to take part in the attack and said Western powers will have to study "options" if Syria's government uses chemical weapons again.
The president was in a "good mood" and continuing his work in Damascus, agencies cited the lawmakers as saying, and praised the Soviet-era air defence systems Syria used to help to repel the Western attacks.
By morning, the Western countries said their bombing was over for now.

The United States has warned Syria's government that it is "locked and loaded" to strike again if Damascus carries out chemical attacks.
"This is something we can not accept, the use of chemical weapons on civilians", he said, "and the global community needs to continue to stand extremely strongly as we continue to hold Syria accountable".
The Syrian leadership denied any involvement in the attack, and invited the experts from the Organization for the Prohibition of Chemical Weapons (OPCW) to investigate into the reports. It was not clear when the visit would take place. But last night's attack was aimed at the "heart of enterprise", the Pentagon said.
The Russian military had vowed to respond to any attack, and President Vladimir Putin's administration had repeatedly warned Trump was taking America down a risky path.
An worldwide fact-finding mission from the Organization for the Prohibition of Chemical Weapons is now in Syria and expected to visit Douma.
The first of the targets was a research center near the capital city of Damascus; 76 missiles were launched against the center. "It will restore deterrence against further regime use of chemical weapons, at least temporarily".
