Summary:
Since having its boundaries drawn by France after the First World War, Lebanon has struggled to
define its national identity. Unlike other countries in the region, its population included Christian,
Sunni Muslim, and Shia Muslim communities of roughly comparable size, and with competing
visions for the country. Seeking to avoid sectarian conflict, Lebanese leaders created a
confessional system that allocated power among the country’s religious sects according to their
percentage of the population. The system was based on Lebanon’s last official census, which was
conducted in 1932.
As Lebanon’s demographics shifted over the years, Muslim communities pushed for the political
status quo, favoring Maronite Christians, to be revisited, while the latter worked to maintain their
privileges. This tension at times manifested itself in violence, such as during the country’s 15-
year civil war, but also in political disputes such as disagreements over revisions to Lebanon’s
electoral law. To date, domestic political conflicts continue to be shaped in part by the influence
of external actors, including Syria and Iran.
The United States has sought to bolster forces that could serve as a counterweight to Syrian and
Iranian influence in Lebanon. The United States has provided more than $1.7 billion in military
assistance to Lebanon with the aim of creating a national force strong enough to counter nonstate
actors and secure the country’s borders. Hezbollah’s armed militia is sometimes described as
more effective than the Lebanese Armed Forces (LAF), and has also undertaken operations along
the border to counter the infiltration of armed groups from neighboring Syria. U.S. policy in
Lebanon has been undermined by Iran and Syria, both of which exercise significant influence in
the country, including through support for Hezbollah. The question of how best to marginalize
Hezbollah and other anti-U.S. Lebanese actors without provoking civil conflict among divided
Lebanese sectarian political forces has remained a key challenge for U.S. policymakers.
In addition, Lebanon currently faces a large-scale refugee crisis driven by the ongoing war in
neighboring Syria. There are over 1 million Syrian refugees registered with the U.N. High
Commissioner for Refugees (UNHCR) in Lebanon, in addition to a significant existing
community of Palestinian refugees. This has given Lebanon (a country of roughly 4.3 million
citizens in 2010) the highest per capita refugee population in the world. Lebanon’s infrastructure
has been unable to absorb the refugee population, which some government officials describe as a
threat to the country’s security. Since 2015, the government has taken steps to close the border to
those fleeing Syria, and has implemented measures that have made it more difficult for existing
refugees to remain in Lebanon legally.
At the same time, Hezbollah has played an active role in the ongoing fighting in Syria. The
experience gained by Hezbollah in the Syria conflict has raised questions about how the eventual
return of these fighters to Lebanon could impact the country’s domestic stability or affect the
prospects for renewed conflict with Israel.
This report provides an overview of Lebanon and current issues of U.S. interest. It provides
background information, analyzes recent developments and key policy debates, and tracks
legislation, U.S. assistance, and recent congressional action.
