So far, the war in Syria has proved expensive but not destabilizing for Jordan, in large part because Amman has extensive experience dealing with both refugees and foreign-borne subversion. If the situation in the north deteriorates further, however, the kingdom's security and humanitarian infrastructure may struggle to keep up. Of particular concern is potential acceleration in the cross-border flow of refugees and foreign jihadists, as well as the possibility that Bashar al-Assad's regime could lose control of its chemical weapons stockpiles.
In spring 2012, Jordan responded to the growing tide of Syrian refugees by building the Zaatari camp near the northern town of Mafraq. When it opened in July, its capacity was around 113,000, according to the Office of the UN High Commissioner for Refugees (UNHCR). Although the majority of Syrians entering the kingdom have avoided Zaatari and instead taken up residence in Jordan's largest cities, the most destitute migrants have converged on the camp.
According to Prime Minister Abdullah Nsour, over 300,000 Syrians have entered Jordan since the war began, including 36,000 in 2013 alone. Yet Amman considerably overstated its refugee counts during the last Iraq war, raising doubts about its Syria figures. UNHCR statistics indicate that around 25 percent of the roughly 600,000 Syrians who have fled the conflict are now in Jordan, but this figure only accounts for registered refugees. In any case, nearly 85,000 temporary residents are reportedly being housed in Zaatari, and the kingdom has commenced construction of a second camp capable of housing 30,000 near Zarqa.
Zaatari has proven highly controversial since its establishment. Although UNHCR has primary responsibility for administering the camp, the agency's efforts there are dramatically underfunded, leaving Amman to shoulder the financial burden. Nsour recently told Jordanian daily al-Ghad that building the camp and hosting its residents has cost around $500-600 million thus far, and that the kingdom has received less than $200 million in international assistance toward these expenses.
Despite Jordan's efforts to accommodate its guests, Zaatari's inhabitants are clearly dissatisfied. Although the camp provides the required basic services (food, shelter, education), it is quite rudimentary. In October and December, as winter set in, refugees set dozens of tents on fire to protest the poor conditions. Then, in early January, floods swamped the camp and damaged 500 of its 4,500 tents. Worse, a family of seven was killed later that month when a kerosene heater mishap resulted in a fire. Several infants have died recently as well, spurring a government press conference at which Health Minister Abdul Latif Wreikat assured a skeptical public that hypothermia was not the cause of death.
Short on funds and suffering an economic crisis, Jordan is not solely to blame for these conditions. Still, the Islamist opposition daily al-Sabil has been relentlessly attacking the government, giving the impression that Zaatari is more a concentration camp than a refugee camp.
A less-publicized problem is the nearly 500,000 Palestinian refugees in Syria, many of whom have been denied sanctuary in Jordan due to demographic sensitivities. Already divided between the kingdom's own East Bank tribal and Palestinian-origin communities, Amman is loath to further skew the balance in the latter's favor.
More broadly, the palace fears a mass influx of refugees of any origin. On January 18, in a development reminiscent of Amman's 1990 policy toward displaced Iraqis, Information Minister Samih Maaytah announced that if the Assad regime falls or chaos spreads, Jordan will stop taking in refugees, instead providing humanitarian assistance on the Syrian side of the border.
Jordan has reinforced its northern border in recent months, sending thousands of additional troops to the frontier not only to protect fleeing Syrians, but also to prevent terrorist infiltration. In October, Amman announced that a Jordanian soldier had been killed by local Islamist extremists heading north to join the Syrian rebels. And in December, Jordanian and Syrian forces reportedly exchanged fire near the Ramtha border crossing.
More troubling, however, is the threat posed by foreign Islamist militants entering the kingdom to perpetrate attacks, or Jordanians affiliated with al-Qaeda plotting the same. Even before the uprising, Assad's Syria was a favorite launching point for terrorist operations against Jordan -- the 2002 assassination of U.S. diplomat Laurence Foley and the foiled 2005 chemical attack by the Qaeda-affiliated Jayousi Cell were both initiated there. And last October, Amman interdicted eleven Jordanian nationals who had brought explosives from Syria to attack Western targets and malls in the Abdoun neighborhood of the capital, where the U.S. embassy is located.
The kingdom also has a long history of terrorist spillover from post-Saddam Iraq, including a November 2005 hotel bombing that killed sixty -- an attack known as "Jordan's 9/11." For that reason alone, Assad's fall would likely mean more terrorism for Jordan and an increase in indigenous Salafist recruitment.
Increased troop deployments and refugee costs have been difficult for Jordan to absorb given its ongoing financial crisis -- the kingdom had a 30 percent budget deficit in 2012 and sought to implement an austerity program involving extremely unpopular cuts to food and fuel subsidies. But the war in Syria has carried several less obvious costs as well.
