While Geneva - which calls for the installation of a transitional government, the writing of a new constitution, and ultimately democratic elections - has foundered, Russia, Iran and Turkey have started their own peace process for Syria, which would be likely to keep Assad in power. Britain also scheduled an emergency cabinet meeting.
The rest of the world is braced for an expected strike by the United States and its allies against Syria, as Trump taunts Moscow with the prowess of American weaponry and a Kremlin envoy warns that Russian Federation could shoot U.S. missiles down. Get ready Russian Federation, because they will be coming, nice and new and "smart!"

"Either of those actions are created to interfere with an investigation that may implicate the President", House Intelligence Committee ranking member Adam Schiff said on CNN's "The Situation Room".
But while the Russian president's lieutenants continued to up the ante with threats and allegations, Vladimir Putin himself adopted a more statesmanlike tone, in remarks to new ambassadors presenting their credentials at the Kremlin.
Trump said Monday he would decide "over the next 24 to 48 hours" on his response to Syria. He told Russia: "You shouldn't be partners with a Gas Killing Animal who kills his people and enjoys it!"
