Over a decade at the helm of the Arab world’s most populous country, there have been times when President Abdel Fattah el-Sisi of Egypt looked like a man dangling from a ledge by the tips of his fingers.

There was the time 10 years ago, for instance, when the former general seized power by deploying the army to depose Egypt’s first freely elected president, a takeover capped by the killing of at least 800 anti-coup protesters in a single day. The Rabaa massacre, as it became known, brought a storm of international condemnation down on Mr. el-Sisi’s head.

Or take the economic meltdown of the last 21 months, when the currency crashed, prices shot skyward and many Egyptians stopped being able to afford meat or their children’s school fees. Though the International Monetary Fund offered a bailout to help cover colossal debts run up by the president, lenders and Egyptians alike seemed to be fast losing patience with what experts called Mr. el-Sisi’s ruinous management.

Yet, a decade later, he is still president — and back for six more years, as the results of this month’s presidential election confirm. The authorities said on Monday that Mr. el-Sisi had won a third term with 89.6 percent of the vote.
