President Donald Trump’s national security adviser, Lt.

Gen. H.R. McMaster, is advocating for “more active, forceful, more aggressive” foreign policy in Syria, according to CNN’s Brooke Baldwin.

McMaster wants to “move the country away from a containment model to a regime change model,” according to a source.

“If we have to do it, it’s because it is the right thing to do,” McMaster told CNN.

“It’s not just about the short-term and short-run.”

McMaster’s comments come as the White House continues to push for a diplomatic solution to the war in Syria.

Trump has been urging the international community to get involved and even calling for a UN-led military strike.

The White House also said Tuesday that the U.S. will “work with our partners” to help train and equip Syrian rebels.

“We’re going to do more than train and arm Syrian rebels,” Trump said in a speech Tuesday.

“In fact, we’re going further than that.

We’re going do more and we’re not going to stop until we get the Syrian people back to their country.”

“What I want to do is to work with our allies in the region and in the world to make sure that there is no place for the use of chemical weapons,” he added.
