Trump has said, “I’m very capable of changing to anything I want to change to.” In the case of Syria, however, he seems to have acted without a clear plan in place. During the campaign, he promised to “bomb the shit out of” isis, which holds territory in Syria, but he also said that it was foolish to become mired in the civil war, or to target Assad, who has opposed isis—at least, rhetorically. As recently as March 30th, Secretary of State Rex Tillerson said that Assad’s future would be “decided by the Syrian people,” words that signalled a sharp departure from Obama’s insistence that Assad must leave office. Then, last Thursday, Tillerson seemed to shift direction, saying that “it would seem there would be no role” for Assad in Syria’s political future. But he later said, “I would not in any way attempt to extrapolate that to a change in our policy or our posture relative to our military activities in Syria today.”

So far, President Trump has not gone beyond the declaration that he "will absolutely do safe zones" for the Syrian people. It's an idea he broached in November 2015 as a candidate, when he proposed building "a big beautiful safe zone and you have whatever it is so people can live, and they'll be happier."
And they all lived ever happily after, from the same article
The last option would be extremely perilous -- given the Russian presence and the hostility of Syrian President Bashar al-Assad's regime -- and requires the injection of a substantial number of US military forces.
The Kremlin warned Thursday that "Washington must think about the potential consequences of establishing safe zones." Russia is perennially suspicious of Western plans to orchestrate regime change (think Libya, Serbia) disguised as humanitarian help.
And it is true most of the interventions based around humanitarian help are frontrunners for covert operations.

The president also indicated that he had changed his mind about the country's leader, President Bashar al-Assad, for whom he had expressed support for "killing ISIS," though saying he didn't like him.
"I like to think of myself as a very flexible person. I don't have to have one specific way, and if the world changes, I go the same way," Trump said. "It's already happened, that my attitude towards Syria and [President Bashar al-]Assad has changed very much."
In the last week of the election, Trump worked Syria into a few of his campaign speeches, using it as a dig at Clinton.
"Now she wants to start a shooting war in Syria in conflict with nuclear-armed Russia. Frankly, it could lead to World War III and she has no sense," he said at a rally in Miami on Nov. 2.
I dont mind this thinking: move carefully in that area because there is so much below the surface than above
In an interview with The New York Times on Nov. 23, Trump said he had "some very strong ideas on Syria," but refused to publicly give specifics.
"I can only say this: We have to end that craziness that’s going on in Syria," he said, before taking the conversation off the record.
In a Jan. 25 interview with ABC News’ David Muir in the White House, Trump said that he’ll “absolutely do safe zones” to provide a space for refugees fleeing the conflict.
The reality is he has only had an opinion on the dangers of getting involved in Syria and the dangers the refugee issue creates. Both of them valid and neither of them ( to me) a good reason to remove people already in place. Certainly the ideal is a for Syria to oust Assad on their own , but then why dont people ask Russia to leave as well?
