And the Kremlin said Russian President Vladimir Putin and Iran's leader Hassan Rouhani condemned the cruise-missile attack Thursday on Syria's Shayrat airfield and urged the United Nations Security Council to take action against the USA for launching the attack that violated "the sovereignty of an independent country".
It's not clear what the next move will be for the U.S.
McCain also said he does "not agree" with Tillerson's position that the U.S. As a somber Trump noted, the world could not let such a violation of the Chemical Weapons Convention - not to mention civilized norms - go unpunished.
"Russians should ask themselves: 'What are we doing here?
So, I think he will stop, but very serious damage was done to Russia-US relations and now there is a question: should [US Secretary of State Rex] Tillerson come to Moscow and what should we talk about after this?"
Pressed to clarify Sunday, National Security Adviser Lt. Gen. H.R. McMaster said the goals of fighting ISIS and ousting Assad were somewhat "simultaneous" and that the objective of the missile strikes were to send a "strong political message".
But Secretary Tillerson called Russian Federation "incompetent" for allowing Syria to hold on to chemical weapons in interviews on Sunday, while America's United Nations ambassador Nikki Haley told CNN her country wanted regime change.
On whether Assad should be removed from power, McMaster said: "We are not saying that we are the ones who are going to effect that change".
At least 70 people died in what the United States says was a chemical weapons attack in rebel-held Syria.
Graham said he supports the president's decision to order the strikes, but wants to see more from the administration on Syria. But given the fact that Assad has been blamed for carrying out dozens of chemical attacks over the past few years, so does the new president think a barrage of cruise missiles will make any difference?
Syria and Russian Federation each condemned the US attack. He is saying that he will not hold all the might of the United States military on a tight leash when there are such deliberate and cruel provocations.
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.
Although there is no evidence to say Russian Federation was involved, a senior official said that "at a minimum, Russian Federation failed to reign in the Syrian regime".
"Congress needs to work with the president to try and deal with this long-term strategy, lack of strategy, really, in Syria", he said.
"The Arab League rejects regional and global powers' attempts to politick over the corpses of Syrians or at the cost of its sovereignty", he told reporters.
"If you violate global agreements, if you fail to live up to commitments, if you become a threat to others, at some point a response is likely to be undertaken", he told ABC's "This Week".
