Because if Assad again is caught using chemical weapons, he should feel American wrath.
"Could not have had a better result".
The main U.S. role in Syria has been to lead the coalition attacking Islamic State militants, who moved into the vacuum of a near-lawless country but now have been driven from their territory.
His choice of words recalled a similar claim associated with President George W. Bush following the US-led invasion of Iraq. Bush addressed sailors aboard a Navy ship in May 2003 alongside a "Mission Accomplished" banner, just weeks before it became apparent that Iraqis had organized an insurgency that would tie down US forces for years.
When asked whether Britain would join the United States if Washington decided on further military action in Syria, May declined to answer the question directly but said: "We believe that those responsible should be held to account".
The White House press secretary, Sarah Huckabee Sanders, said in a brief statement after Trump met with Mattis and other members of his National Security Council: "No final decision has been made".
There were signs of a global effort to head off a direct confrontation between Russian Federation and the West.
In April a year ago Trump ordered Tomahawk strikes on the Shayrat Airbase in response to a similar chemical weapons attack on rebel-held Khan Sheikhun.
May said, "We can not allow the use of chemical weapons to become normalized". That sealed a major victory for Assad in the war, crushing a protracted rebellion in the eastern Ghouta region near the capital Damascus.
The strikes "successfully hit every target", Ms White told reporters at the Pentagon. "The situation is tense", Peskov said, adding that Russian Federation is calling for an "unprejudiced and objective investigation before making judgements" on the suspected use of chemical weapons.
Trump on Monday called the weekend chemical attack in Syria "atrocious" and said the US will make "major decisions" about its response soon. His Russian and Iranian backers will ensure that. The U.S. government has not generally supported arguments by human rights advocates for humanitarian interventions. Chemical weapons are another trick in his book.
German Chancellor Angela Merkel called the attack "necessary and appropriate".
Nervous world stock markets showed signs of recovery after Trump signaled military strikes might not be imminent.
On Saturday morning, French Defense Minister Florence Parly said that French fighter jets took off from multiple bases in France for the strike.
"France will not allow any escalation that could harm the stability of the region as a whole but we can't let regimes that think they can do everything they want, including the worst things that violate global law, to act", Macron said. "The president holds Syria and Russian Federation responsible for this chemical weapons attack".
The Syrians said as many as 16 people were killed in the strikes, including nine civilians in the surrounding area.
When pressed, he acknowledged that some unspecified portion of Assad's chemical arms infrastructure was not targeted.
Two US officials said attacks could continue beyond tonight, with a senior administration official saying "this isn't over". However, I think there's less to it than meets the eye.
Mr Assad's Barzah research and development centre in Damascus was destroyed, Mr McKenzie said. "It does not exist anymore".
"New, stealthy JASSM missiles could be delivered by B-1B and B-52 (and now likely F-15E and F-16)", Mount said.
Syria's Foreign Ministry said Wednesday that Trump's threats to attack are "reckless" and endanger worldwide peace and security.
The attack has drawn condemnation from Western leaders, with President Donald Trump vowing Monday to come to a decision "over the next 24 to 48 hours" on how to make Syria pay a "big price". "We're still working on this", he said.
McKenzie said 105 U.S. and allied missiles were fired, of which 66 were Tomahawk cruise missiles launched from aboard three U.S. Navy ships and one Navy submarine.
NBC News reported that USA officials obtained blood and urine samples from victims of the Douma attack that tested positive for chemicals, mainly for chlorine and some for a nerve agent.
A team of experts from the global chemical weapons watchdog, the Organisation for the Prohibition of Chemical Weapons, was traveling to Syria and will start their investigations on Saturday, the Netherlands-based agency said. Last month's attack with Russia's Novichok nerve agent on former Russian spy Sergei Skripal and his daughter, in the British town of Salisbury, comes to mind.
"We're still assessing the intelligence, ourselves and our allies".
America has deployed its Carrier Strike Force USS Harry Truman from Norfolk, Virginia, along with other warships.
