BEIRUT -- As U.S. troops beef up in eastern Syria to protect oil fields, residents hope their mission will bring stability and prosperity to the remote and resource-rich region --and keep the Syrian government out.
Their hopes reflect the expectations being piled onto the operation, even as President Donald Trump flip-flopped on the scope and duration of troops deployment. He initially ordered all troops out of Syria last month, then decided to keep a force in place to hold the oil infrastructure.
That keeps the U.S. troops in the middle of eastern Syria's complex political geography, rich in oil and gas and packed with Turkish, Kurdish, Russian, Syrian and Iranian-backed troops.
The stretches of Syria east of the Euphrates, where the oil is located, have been lost to the government of Syrian President Bashar Assad for most of the country's eight-year civil war.
Its mostly Arab population is opposed to Assad, angry with years of neglect that impoverished the area despite its resource wealth. Since U.S.-backed Kurdish-led forces drove out the Islamic State group, it has been governed by a Kurdish-led administration.
So when Turkey invaded northeastern Syria last month, hundreds held angry protests in towns and villages in the east -- not against Ankara but against the Syrian government and its Iranian allies. They feared the invasion would empower Damascus to send troops to their areas and restore control.
Residents welcomed Trump's latest decision, believing it a shield that would bring investments and an economic boom.
"Good things are coming," said Shehab, a 20-year-old who works as a herder and farmer in a small town in Deir el-Zour province, home to the largest oil fields.
"Deir el-Zour lives on a sea of oil. We are optimistic that if the U.S. takes over the fields, they will bring in (new) companies and expertise," Shehab said. "The unemployed will find jobs." He declined to give his last name for security reasons.
Trump has vowed to strike a deal with "Exxon Mobil or one of our great companies to go in there" and modernize the oil fields.
But experts say it is unlikely a U.S. oil major would find it commercially attractive or politically stable to invest there. Some in eastern Syria have hoped regional countries interested in gaining clout in Syria, such as Saudi Arabia, may be interested.
Syria's oil reserves are modest, estimated in 2011 at around 2.5 billion barrels. Production shrank from a peak of 380,000 barrels a day to an estimated 80,000 now, and the fields are in disarray from years of conflict and mismanagement. Currently, the Kurdish-led administration sells the oil on the local market or through smuggling it to the Syrian government.
Pentagon officials indicated the U.S. presence is not intended to improve the oil infrastructure but to keep it in the hands of the Kurdish-led Syrian Democratic Forces.
Chief Pentagon spokesman Jonathan Hoffman said Thursday the U.S. mission is focused on two things: Preventing IS from recapturing the oil fields and enabling the SDF to maintain a revenue source to continue fighting the militants.
"The revenue from this is not going to the U.S.," Hoffman said.
From the ground, the new U.S. mission blocks Damascus' plans to regain the east and Iran's efforts to complete a land corridor through Iraq, Syria and Lebanon. Iran's ability to project power and potentially transport advanced weaponry all the way to Israel's doorstep has long been a major U.S. concern.
