Event if Trump did, al-Atrash added, it could not disrupt the rapport among Syrian people, army and government.
"U.N. resolutions have been taken, and today we might be outside the framework of these resolutions, but we are within the framework of worldwide law: This dictator is murdering his own people", Jean-Jacques Bridey, head of the French parliament's defence commission, said this past week.
In April previous year Trump ordered Tomahawk strikes on the Shayrat Airbase in response to a similar chemical weapons attack on rebel-held Khan Sheikhun. Then Thursday he tweeted that an attack on Syria "could be very soon or not so soon at all!"
Mr. Mattis' remarks at a House Armed Services Committee hearing followed a series of Trump tweets this week that initially indicated he was committed to bombing Syria but later suggested he was awaiting further advice and assessment.
Macron said Thursday that France has proof that the Syrian government launched chlorine gas attacks and said France would not tolerate "regimes that think everything is permitted".
Mr. Mattis said that although the United States has no hard proof, he believes the Syrian government was responsible for Saturday's attack.

In response, Trump tweeted that while Russian Federation vowed to protect Syria against attack, "Get ready Russian Federation, because [attacks] will be coming, nice and new and "smart!"
The Organisation for the Prohibition of Chemical Weapons, based in the Netherlands, announced it was sending a fact-finding team to the site of the attack outside Damascus, and it was due to arrive Saturday.

A French frigate, UK Royal Navy submarines laden with cruise missiles and the USS Donald Cook, an American destroyer equipped with Tomahawk land attack missiles have all moved into range of Syria's sun-bleached coast.
As tensions mount between the U.S. and Russian Federation over a possible USA strike, the Kremlin said a crisis communications link with the United States meant to avoid an accidental clash over Syria was being used by both sides.
The remarks came a day after US President Donald Trump warned Russian Federation that his country would launch missile attacks on Syria after the alleged chemical attack took place. On Wednesday he went even further, warning Russian Federation "to get ready" after Moscow vowed to shoot down any missiles fired at Syria.
