At risk could be the future of a transitional government run by those who drove Syrian leader Bashar Assad from power late last year and hopes that it can stabilize the country after a devastating 13-year civil war that has left millions dead or displaced, the economy in ruins and thousands of foreign fighters still on Syrian soil.

U.S. presidents have piled up penalties over the years on the autocratic family that previously controlled Syria, and those could be quickly lifted or waived through executive action. But Congress imposed some of the strictest measures and would have to permanently remove them.

Syrian President Ahmad al-Sharaa, the former militant commander who led the overthrow, says he is working to build an inclusive government friendly to the West. Some Trump administration officials are pushing to lift or waive sanctions as fast as possible without demanding tough conditions first.

Others in the administration have proposed a phased approach, giving short-term waivers soon on some sanctions and then tying extensions or a wider executive order to Syria meeting conditions, which could substantially slow — or even permanently prevent — longer-term relief. That would impede the interim government’s ability to attract investment and rebuild Syria after the war, critics say.

“The Syria sanctions are a complex web of statutes, executive actions and United Nations Security Council resolutions that have to be unwound thoughtfully and cautiously,” White House National Security Council spokesman Max Bluestein said.

The administration is “analyzing the optimal way to do so,” Bluestein said in a statement Thursday.

An announcement on a first round of measures to ease sanctions could come as soon as Friday or on Tuesday, after the Memorial Day weekend, according to two U.S. officials familiar with the discussions. They spoke on condition of anonymity because they were not authorized to speak publicly.

A State Department proposal circulated among officials following Trump’s pledge on his Middle East trip last week lays out sweeping requirements for future phases of relief or permanent lifting of sanctions, including dismantling Palestinian militant groups as a top demand, according to one of the U.S. officials familiar with the plan.

Additional proposals are circulating, including one shared this week that broadly emphasized taking all the action possible, as fast as possible, to help Syria rebuild, the official said. Besides sanctions waivers, discussions include easing restrictions on banking and business and lifting longstanding U.S. terrorist designations.A welcome US announcement in Syria

People danced in the streets of Damascus after Trump announced in Saudi Arabia last week that he would be ordering a “cessation” of sanctions against Syria.

“We’re taking them all off,” Trump said a day before meeting the country’s new leader. “Good luck, Syria. Show us something special.”

This week, Secretary of State Marco Rubio advocated for a hedged approach in testimony before U.S. lawmakers.

Rubio pushed for sanctions relief to start quickly, saying Syria’s five-month-old transition government could be weeks from “collapse and a full-scale civil war of epic proportions.”

But asked what sanctions relief should look like overall, Rubio gave a one-word explanation: “Incremental.”

Washington had levied sanctions against Syria’s former ruling family since 1979 over its support for Hezbollah and other Iranian-allied militant groups, its alleged chemical weapons program and its brutality against civilians.

The sanctions include penalties for outside companies or investors doing business there. Syria needs tens of billions of dollars in investment to restore its battered infrastructure and help the estimated 90% of the population living in poverty.

Syria’s interim leaders “didn’t pass their background check with the FBI,” Rubio acknowledged to lawmakers this week. The group that al-Sharaa led, Hayat Tahrir al-Sham, was originally affiliated with al-Qaida, although it later renounced ties and took a more moderate tone. It is still listed by the U.S. as a terrorist organization.

But al-Sharaa’s government could be the best chance for rebuilding the country and avoiding a power vacuum that could allow a resurgence of the Islamic State and other extremist groups.

“If we engage them, it may work out, it may not work out. If we do not engage them, it was guaranteed to not work out,” Rubio said.

Mouaz Moustafa, executive director of the U.S.-based Syrian Emergency Task Force and an advocate who has been influential in helping shape past U.S. policy on Syria, said he has been circulating a framework for a proposed executive order that would allow Trump to quickly remove many of the sanctions.

Moustafa asserted that some in the administration were trying to “water down” Trump’s pledge, which he said was aimed at “preventing a failed state and ending perpetual violence.”Debate within the Trump administration

The initial document sent out last week by the State Department’s policy and planning staff proposed a three-phase road map for sanctions relief, starting with short-term waivers. Progress toward additional relief and an outright lifting of penalties in future phases would be tied to tough conditions that generated pushback from some officials.

Removing “Palestinian terror groups” from Syria is first on the list of requirements to get to the second phase. Supporters of sanctions relief say the condition might be impossible, given the subjectivity of determining which groups meet that definition and at what point they can be declared removed.

Other conditions for moving to the second phase are for the new government to take custody of detention facilities housing Islamic State fighters and to carry out a recent deal with U.S.-backed, Kurdish-led Syrian Democratic Forces — which manages the detention facilities — that includes incorporating it into the Syrian army.

To get to phase three, Syria would be required to join the Abraham Accords — normalized relations with Israel — and to prove that it had destroyed the previous government’s chemical weapons.

Israeli Prime Minister Benjamin Netanyahu previously pushed for the Trump administration not to lift sanctions on Syria. Israel has been suspicious of the new government, although Syrian officials have said publicly that they do not want a conflict with Israel.

Since Assad fell, Israel has launched hundreds of airstrikes and seized a U.N.-patrolled buffer zone in Syria.Congressional sanctions on Syria will take much longer to lift

The most difficult penalty to lift could be the Caesar Syria Civilian Protection Act, a wide-reaching set of sanctions passed by Congress in 2019 in response to alleged war crimes by Assad’s government.

It specifically blocks reconstruction activities, and although it can be waived for 180 days by executive order, investors are likely to be wary of reconstruction projects when sanctions could be reinstated after six months.

In a meeting last week in Turkey with Syria’s foreign minister, Rubio and Republican Sen. Lindsey Graham said permanent relief would require action by the Syrian government to meet conditions that the president laid out, according to other U.S. officials, who spoke on condition of anonymity to discuss internal deliberations.

“We have a moment here to provide some capability to this new government that should be conditions-based,” Graham said this week. “And I don’t want that moment to pass.”
