But how likely are the Egyptian armed forces to stage a coup d’état? Coups are an intriguing political phenomenon and have puzzled social scientists ever since the Arab world became the scene of about 40 of them in the decades between 1945 and 1979. Statistics tell us that Arab coups happen mostly in the summer (July and August); they are typically carried out by colonels, not generals; and they usually do not aim at changing the political system (called a breakthrough coup) but at removing a leadership considered to be corrupt, inefficient, or incompetent (called a guardian coup). Most importantly, coups take place only when motivation and feasibility come together.

Military organizations having a certain mindset, motivations can include self-interested considerations such as economic or political aspects. The military’s corporate outlook emphasizes nationalism and unity. It is the antithesis of political parties, which it tends to see as divisive agents. This explains why coups are always performed by professional armed forces, and never by militias or conscripts. The armed forces can appeal to a popular longing for people to stand together that politics cannot satisfy.

Feasibility, in turn, is a combination of opportunity and capacity. Opportunity arises especially when a government is seen as performing poorly in economic terms, and when it is seen as illegitimate—although legitimacy in this context can be acquired not just by democratic means, but also by an extended stay in power. Capacity, however, consists of the ability of military officers to act and command troops cohesively. This implies a high degree of unity as well as a collective agreement to act outside the constitutional order. Put simply: the armed forces act when they can and want to.

In the case of Egypt, the capacity to act is certainly there. The last two years have clearly shown that for this highly corporate organization, there is no issue of lack of cohesion. At the same time, the military’s motivation for a coup is also growing. Its economic interests were already jeopardized under Mubarak’s regime—which partly explains their action against him in 2011—and continue to be harmed by Egypt’s economic free fall. Furthermore, the army sees itself as an independent political actor regardless of Morsi’s attempts to curb its influence. It has stressed repeatedly its responsibility toward Egypt as a state as opposed to its government.

After demonstrators and security forces clashed in front of the presidential palace last December, Defense Minister Abdel Fattah el-Sissi arguably overstepped his mandate by calling for a political dialogue. One month later, he stressed that “the continuation of the conflict between the different political forces and their differences over how the country should be run could lead to the collapse of the state and threaten future generations.” This quote perfectly reflects the Egyptian officers’ mindset: they feel they are accountable only to the nation, or, as the popular saying goes, “the army and the people are one hand.” It is for this reason that the military, when called on by the president to enforce a curfew in Port Said and Ismailia, played football with the protesters, rather than sending them home.

Egyptian military sources now say that they feel that the population is calling on them to do their duty, although they declare that “the popular call has to be very clear before we act.” The widespread public criticism the military encountered in the months between Mubarak’s forced resignation and Morsi’s election has left this institution, unaccustomed as it is to a rift with the public, bruised.

These same military sources also worry that a coup would lead the EU and the United States to suspend their cooperation programs with Egypt, as happened with Mauritania in 2008. That would endanger Egypt’s fragile economy even further and therefore create even more instability. As motivation and capacity for a coup d’état are clearly growing, the only way to prevent another Egyptian putsch is to decrease its feasibility. The only way to do that, however, is by restarting the economy and bolstering the government’s legitimacy. To achieve this, Morsi is running out of time.
