Syrian President Ahmed al-Sharaa met with Republican Congressman Brian Mast on Sunday, intensifying efforts to repeal the US Caesar sanctions ahead of his visit to the White House. Mast, a pro-Israel representative from Florida, has become a significant obstacle to the repeal of the 2019 Caesar Act, which imposed severe economic penalties on Syria following evidence of human rights violations by a Syrian defector. Despite former President Donald Trump’s May pledge to lift sanctions and a subsequent 180-day waiver issued in June, the law remains in effect and can only be fully repealed by Congress. Business leaders and diplomats argue that the uncertain status of the sanctions is hindering investment in Syria, where the economy is struggling. The World Bank estimates Syria’s reconstruction costs at $200 billion, but Gulf states’ pledged investments have been slow to materialize due to the sanctions. Reports suggest Mast’s stance is influenced by lobbying from Israeli Prime Minister Benjamin Netanyahu’s advisor, Ron Dermer. Mast, a US Army veteran who lost both legs in Afghanistan, has a strong connection to Israel, often wearing an Israeli army uniform in Congress. Israel has capitalized on Syria’s instability, occupying a UN buffer zone and conducting air strikes reaching Damascus. Additionally, Israel has positioned itself as a protector of Syria’s Druze minority, backing Druze leader Sheikh Hikmat Salaman al-Hajri with arms. During recent Druze-Bedouin conflicts, Israel blocked Sharaa’s deployment of Sunni security forces, angering Saudi Arabia, Turkey, and the Trump administration. Sharaa’s meeting with Mast was reportedly arranged by supporters of Trump, who is pushing Congress to lift the sanctions. Although Congress is currently in recess due to a government shutdown, efforts are underway to amend the 2026 Defense Act to repeal the sanctions. Mouaz Moustafa of the Syrian Emergency Task Force emphasized the need for a “clear-cut repeal” to restore investor confidence, warning that any possibility of sanctions returning would deter companies from entering Syria.
