A joint command center made up of the forces of Russia, Iran and militias supporting Syrian President Bashar al-Assad on Sunday said the USA strike on a Syrian air base on Friday crossed "red lines" and it would respond to any new aggression and increase its support for its ally.
"In no way do we see peace in that area with Assad as the head of the Syrian government", Haley told NBC's "Meet the Press".
Ms Haley said that the decision to launch the missile strikes had been to tell Syrian president Bashar al-Assad that "enough is enough" and to let Russian Federation know that is was no longer acceptable to "cover for the regime" anymore.
The deadly sarin gas attack in Syria that killed 84 people changed the administration's mind.
Graham also suggested that Trump has the authority, without authorization from Congress, to send in additional troops and hit Assad again for using chemical weapons.
And other members are keen to establish clarity over the U.S.'s position on Assad's regime, ahead of a visit to Russian Federation by U.S. Secretary of State Rex Tillerson on Tuesday.
It will be their first face-to-face encounter since U.S. cruise missiles slammed into a Syrian airbase early Friday Damascus time in retaliation for a suspected sarin gas attack on April 4 that killed at least 87 civilians in Syria's northern Idlib province.
But President Vladimir Putin has not personally condemned the US airstrike, and some reports suggest he is unhappy that Assad has boxed him into defending what many consider a war crime. "We should not be focusing on Syria", Trump told Reuters in an interview last October. After she criticized Russian Federation for not caring about dying children, last week the ambassador was heckled by an audience member at a conference because Trump's now-halted executive order on immigration stopped the USA refugee program for at least 120 days.
"What we are saying is other countries have to ask themselves some hard questions".
The South Carolina Republican and military hawk is calling for as many as 6,000 more USA troops to help defeat the Islamic State terror group in the Middle East.
Moscow has sought to deflect blame from its long-time ally Assad over the incident and says Syrian jets struck a rebel arms depot where "toxic substances" were being put inside bombs. "I think the president has authorization to use force. But until then, you have to prove to me that these people are being vetted in a way that we're not putting American citizens at risk, '" she argued.
However, "whether Russian Federation was complicit here or whether they were simply incompetent or whether they got outwitted" by the Syrian government, they had "failed in their commitment to the global community", he said.
