The UN Security Council, tasked with maintaining global peace and security, has been riven, with Moscow virulently denying the Douma attack took place, or postulating that it was carried out by rebels.
The drumbeat of military action appeared to grow louder, as Russian Federation stonewalled diplomatic efforts at the United Nations and France declared "proof" that Moscow's Syrian ally carried out a deadly chemical weapons attack that killed more than 40 Syrians.
"The position is a very risky one because of Russian involvement, also because we have an erratic president of the United States".
Last night however, the White House said the president was still assessing the American response - with all options remaining on the table. "We're still working on this".
US officials suspect the Russia-backed Assad regime is behind the attack.
He said Foreign Minister Wang Yi had exchanged ideas on the current situation in Syria with visiting United Nations (UN) Secretary-General Antonio Guterres.
But in tweeting about the forthcoming attack, Trump appeared to publicly telegraph military plans - something for which he heavily criticized former President Barack Obama back in 2013. We are totally predictable.
Assad said Thursday that Western threats to strike Syria are based on "lies" and seek to undermine his forces' advances near Damascus. US officials have been consulting with France, Britain and other allies on a possible joint military operation, but the timing remained in doubt Wednesday.
Shortly after his tweeted warning to Russia, Trump took a more conciliatory tone in lamenting that the U.S. -Russia relationship "is worse now than it has ever been".
"We're having a number of meetings today, we'll see what happens, we're obviously looking at that very closely", he told lawmakers and governors in the Cabinet Room.
The U.S., France and Britain have been consulting about launching a military strike. A military operation would be a big deal for Macron, his first military action as president, at a time of heightened domestic tensions over labor law changes. Both the Syrian and Russian governments have said they would support the study.
President Donald Trump has emerged from a meeting with his national security team without a "final decision" on how to respond to a suspected chemical weapons attack in Syria.
The Syrian government denies responsibility.
Referring to the allegation of a Russian military official that there was an attack, but it was staged by the White Helmets brigade component of the rebels in Syria, she said the intelligence provided "certainly paints" a different picture, and the President holds Syria and Russia responsible for the chemical weapons attack.
France already has some 1,100 troops involved in its Operation Chammal, created in 2014 to fight Islamic State extremists in Iraq and extended in 2015 to Syria, as part of the US -led coalition.
