Egyptian Leader's Son Heads to Moscow Jamie Dettmer MOSCOW - Egyptian President Abdel Fattah el-Sissi, dubbed by critics "Putin on the Nile," is set to boost his burgeoning relationship with Russia by dispatching his son, Mahmoud, to Moscow as a military attache, independent regional media outlets are reporting. Russian officials say they welcome the prospect of Mahmoud el-Sissi being based in Moscow. The reassignment would coincide with an open rupture between Cairo and Washington over Egyptian plans to buy advanced Russian warplanes. In Washington, a senior U.S. State Department official Thursday threatened the Cairo government with sanctions if Egypt goes ahead with a $2 billion agreement to purchase more than 20 Su-35 fighter jets, a deal the relocated Mahmoud el-Sissi would likely oversee as military attache. Speaking on condition of anonymity, the official said the Trump administration was still discussing how to address its defense needs with Egypt adding that U.S. officials "have also been very transparent with them in that if they are to acquire a significant Russian platform like the Sukhoi-35 or the Su-35, that puts them at risk towards sanctions." The United States has provided billions of dollars in economic and military aid to Egypt, a longtime ally, whose military has been operating the U.S.-supplied F-16 fighter. Moving his son to Moscow is seen by Western diplomats here as a signal to Washington by el-Sissi of his intent to go ahead with buying the Su-35s. "He's playing hardball with Washington," said a Western diplomat based here, who asked not to identified for this article. According to independent media, Mahmoud el-Sissi's reassignment, planned for next year, has the added benefit for Egypt's president of moving his son out of the spotlight in Cairo. His role as a top official in the country's domestic and foreign intelligence agency, the General Intelligence Service, has prompted turmoil within that agency, as well as growing public criticism of his father for not curbing his son, who has also been drawing allegations of corruption. General Intelligence Service sources told Mada Masr, an Egyptian online newspaper, the reassignment to Moscow is "based on the perception within the president's inner circle that Mahmoud el-Sissi has failed to properly handle a number of his responsibilities and that his increasingly visible influence in the upper decision-making levels of government is having a negative impact on his father's image." Russian President Vladimir Putin has been intensifying his engagement with Middle Eastern and North African leaders, and seeking to rebuild Russian influence in the region, clout that was lost after the collapse of the Soviet Union, according to analysts. Some analysts see the re-engagement as an effort to safeguard established strategic interests. They cite as an example Russian intervention in Syria, where Moscow has its only Mediterranean naval base and needed to prop up the government of President Bashar al-Assad if it wanted to ensure its continuance. .
