NEW YORK – Putting an end to Egypt’s deepening polarization and rising bloodshed requires one urgent first step: the reinstatement of Mohamed Morsi as Egypt’s duly elected president. His removal by military coup was unjustified. While it is true that millions of demonstrators opposed Morsi’s rule, even massive street protests do not constitute a valid case for a military coup in the name of the "people” when election results repeatedly say otherwise.There is no doubt that Egyptian society is deeply divided along sectarian, ideological, class, and regional lines. Yet the country has gone to the polls several times since the February 2011 overthrow of Mubarak’s 30-year rule. The results have demonstrated strong popular support for Islamist parties and positions, though they also make clear the country’s schisms.In late 2011 and early 2012, Egypt held parliamentary elections. Morsi’s Freedom and Justice Party, created by the Muslim Brotherhood, secured a plurality, and the two major Islamist blocs together received roughly two-thirds of the vote. In June 2012, Morsi defeated his rival Ahmed Shafik, Mubarak’s final prime minister, by a margin of 52-48% to win the presidency. In a national referendum in December 2012, a 64% majority of those voting approved a draft constitution backed by the Muslim Brotherhood (though turnout was low).The secular argument that Morsi’s lust for power jeopardized Egypt’s nascent democracy does not bear scrutiny. Secular, military, and Mubarak-era foes of the Muslim Brotherhood have used every lever at their disposal, democratic or not, to block the Islamist parties’ democratic exercise of power. This is consistent with a decades-old pattern in Egyptian history, in which the Brothers – and Islamist political forces in general – were outlawed, and their members imprisoned, tortured, and exiled.Claims that Morsi ruled undemocratically stem from his repeated attempts to extricate the popularly elected parliament and presidency from anti-democratic traps set by the military. After the Islamist parties’ huge victory in the 2011-2012 parliamentary elections, the military leadership and the Supreme Court (filled with Mubarak-era judges) worked to derail the new parliament and prevent it from establishing an assembly to draft a new constitution.The key action came in June 2012, when the Supreme Court, staffed entirely with Mubarak-era holdovers, nullified the results of the parliamentary elections on specious grounds. The military was set to reassert full legislative powers.Morsi’s subsequent victory in the presidential election therefore set up an epic battle over the future of the parliament and the constitution, as Morsi attempted to protect the democratically elected parliament while the military fought to dissolve it. In the end, Morsi insisted that the elected parliament create a constitutional assembly, which produced the draft approved in the December 2012 referendum.As is typical of political revolutions, Egypt’s economic situation has gone from bad to worse in the course of these power struggles. Revolutions tend to confront new governments with steeply rising social demands (for wage increases and higher welfare spending, for example) at a time of capital flight, financial turmoil, and deep disruptions of production. In Egypt’s case, the crucial tourist sector contracted sharply after the revolution. Unemployment soared, the currency depreciated, and food prices rose dangerously.None of this is surprising, and little of it can be managed by a new government that lacks experience, market confidence, and full control of the levers of power. Historically, outside parties have thus played a decisive role. Will foreign governments and the International Monetary Fund extend vital finances to the new government, or will they let it flounder and drown in a tsunami of currency depreciation and inflation?Here, the feckless West – torn between its democratic rhetoric and its antipathy to the Islamists – showed its hand. The result was equivocation and delay, rather than commitment and assistance. The IMF has talked with the Egyptian government for two and a half years since Mubarak’s overthrow without so much as lending a single cent, sealing the Egyptian economy’s fate and contributing to public unrest and the recent coup.It appears from press reports that the West finally gave the green light to the Egyptian military to overthrow Morsi, arrest the Muslim Brotherhood’s leadership, and repress the Islamist rank and file. US President Barack Obama’s unwillingness to stand up for Egypt’s elected leaders, or even to label their overthrow a "coup” (thereby protecting the continued flow of US funds to the Egyptian military), shows that when push came to shove, the West sided with the anti-Islamists in subverting democracy. Of course, in classic Orwellian fashion, the West did so in democracy’s name.Jeffrey D.
