Armed Conflict in Syria: Overview and U.S. Response

"A deadly chemical weapons attack in Syria on April 4, 2017, and a U.S. military strike in response on April 6 have returned the conflict—now in its seventh year—to the forefront of international attention. In response to the April 4 attack, some Members of Congress called for the United States to conduct a punitive military operation. These Members and some others since have praised President Trump’s decision to launch a limited strike, with some calling on the president to consult with Congress about Syria strategy. Other Members have questioned the president’s authority to launch the strike in the absence of specific prior authorization from Congress. In the past, some in Congress have expressed concern about the international and domestic authorizations for such strikes, their potential unintended consequences, and the possibility of undesirable or unavoidable escalation.

Since taking office in January 2017, President Trump has stated his intention to “destroy” the Syria- and Iraq-based insurgent terrorist group known as the Islamic State (IS, also known as ISIL, ISIS, or the Arabic acronym Da’esh), and the president has ordered actions to “accelerate” U.S. military efforts against the group in both countries. In late March, senior U.S. officials signaled that the United States would prioritize the fight against the Islamic State and said that Syrian President Bashar al Asad’s future would be determined by the Syrian people. Nevertheless, in the wake of the April 4 attack, President Trump and senior members of his Administration have spoken more critically of Asad’s leadership, and it remains to be seen whether the United States will more directly seek to compel Asad’s departure from power while pursuing the ongoing campaign against the Islamic State..."

CULTURAL PROPERTY: Protection of Iraqi and Syrian Antiquities

"U.S. agencies and the Smithsonian Institution (Smithsonian) have undertaken five types of activities to protect Iraqi and Syrian cultural property since 2011, which include awareness raising, information sharing, law enforcement, overseas capacity building, and destruction prevention. For example, the Department of Homeland Security reported coordinating with the Federal Bureau of Investigation and other agencies to open 18 Iraqi and Syrian cultural property cases—such as those regarding smuggling by individuals and international criminal organizations—between 2011 and February 2016. To enhance the capacity of partners overseas, the Department of State (State), the government of Iraq, and others established an archaeological and cultural management training facility in Erbil, Iraq. In addition, to prevent destruction, the Smithsonian and others trained Syrian antiquities professionals to use sandbags and other materials to protect ancient mosaics at a Syrian museum, reportedly resulting in the successful protection of the museum collection when it was bombed..."

Counting Casualties in Syria and Iraq: Process and Challenges

"Casualty estimates for the conflicts in Iraq and Syria are inconsistent and unreliable because of a range of methodological challenges in conducting and reporting counts. Estimates of the number of people who have died during Syria's civil conflict since March 2011 range from 250,000 to 470,000. In Iraq, the estimated range is between 19,000 and 41,650 deaths since January 2014. This product discusses the difficulties of collecting war-related casualty data in both countries and provides an overview of some of the current estimated figures available through selected organizations. CRS is unable to independently track casualties in Syria and Iraq, and cannot verify the data presented..."
