Russian Federation and Iran warn U.S. over future 'red lines' in Syria

Criticized for his low-profile diplomacy, Secretary of State Rex Tillerson is emerging from the shadows with a leading public role in shaping and explaining the Trump administration's missile strikes in Syria.

National Security Adviser Gen. H.R. McMaster addressed the apparent difference in his appearance on "Fox News Sunday", saying, "Both Secretary Tillerson and Ambassador Haley are right about this". "I think the Obama administration had a great opportunity to solve this crisis a long time ago when he said the red line in the sand", Trump said.

After last Tuesday's chemical attack, Mr. Trump said his attitude toward Mr. Assad "has changed very much" and Mr. Tillerson said "steps are underway" to organise a coalition to remove him from power.

Syria is at the top of the geopolitical agenda after a surprise decision by U.S. President Donald Trump to launch an airstrike against one of Assad's air bases last week.

Allies of Bashar al-Assad's regime rallied around the Syrian strongman and pledged to respond to US "aggression" after the Trump administration bombed a military airfield in retaliation for a poisonous gas attack.

The mixed signals on Assad's future came as top White House officials all did seem to agree on increasing pressure on Russian Federation.

Even before Trump ordered the strike in retaliation for a nerve gas attack, Tillerson's visit was certain to be dominated by thorny issues.

Those include alleged Russian interference in the 2016 USA presidential election, Washington's accusation that Russia is violating an important arms control treaty, and trying to bridge differences on how to conduct the fight against Islamic State.

"Congress needs to work with the president to try and deal with this long-term strategy, lack of strategy, really, in Syria", he said.

Trump's note said the United States would "take additional action, as necessary and appropriate".

The allegation is grave, even by the standards of the now dismal U.S.

Sen. Lindsey Graham (R-SC) did not mince words - or letters - when he remarked on Bashar al-Assad's flippant attitude toward President Trump on Sunday's "Meet the Press".

He did not comment on reports the U.S. and United Kingdom are ready to offer Moscow the chance to rejoin the G8 if it drops its support for Mr Assad.

It was the first time the U.S. has intervened directly against Assad's government, who is fighting a civil war with the backing of Russian Federation and Iran, and the G7 ministers will deliberate the West's next steps.

Those elements, the senior official said, add to the conclusion that Russian Federation was complicit in the attack.

US Secretary of State Rex Tillerson blames Russia's inaction for helping fuel a deadly poison attack against Syrian civilians last week.

The Geneva Communique calls for a new Syrian constitution and elections, but does not specify the fate of Assad.

"If you look at his actions, if you look at the situation, it's going to be hard to see a government that's peaceful and stable with Assad", she added. And he's set for an even higher-profile mission, heading to Moscow under the twin clouds of Russia's USA election meddling and its possible support for a Syrian chemical weapons attack. He said trust was gone and that relations were "completely ruined" by an action that put them "on the verge of a military clash".
