According to the State Department, the American-led coalition against the Islamic State currently includes 60 states. While the war against IS is, as President Obama said last week, “an operation that involves the world,” all allies are not equal. Among Washington’s many partners, Jordan is perhaps the most important. From deploying fighter jets to providing logistical support to training moderate Syrian rebels, Jordan is proving an indispensable ally in the campaign against ISIS. And for good reason: IS poses an immediate danger to the Kingdom. In recent months, Jordan has arrested dozens of IS supporters, and just weeks ago Jordan witnessed its second pro-IS demonstration.

But not everyone in Jordan supports membership in the coalition. According to a poll published last month by the Center for Strategic Studies at University of Jordan, only 62 percent of Jordanians consider IS—and a mere 31 percent the Syria-based Al Qaeda affiliate Jabhat Al Nusra—to be terrorist organizations. Even more stunning, just 44 percent of Jordanians surveyed say that Al Qaeda is a terrorist group.

Given these sentiments, it’s not surprising that many Jordanians oppose their military’s participation in the campaign targeting IS and Jabhat Al Nusra.

In fact, objections to a Jordanian role in the anti-IS alliance emerged before the state signed up. In the beginning of September, twenty-one members of Jordan's parliament sent a memo to its speaker rejecting the Kingdom’s participation. “This war is not our war,” the representatives wrote. “Our army is able to defend our borders and respond to any aggression.”

The signatories of the memo represent less than 15 percent of the parliament, but based on Center for Strategic Studies data and on anecdotal evidence gathered during my visits to the Kingdom, anti-coalition sentiment is significantly more prevalent among Jordan’s general population.
