Abdel-Fattah el-Sissi actually has some serious credentials, including the The Joint Services Command and Staff College (JSCSC)(UK), and US Army War College.

His career path means that he also likely participated at the staff level in the huge, biannual Bright Star exercises held in Egypt, with the US and 11 other countries. One of the few good things to have come out of the Camp David Accords, these have likely percolated the idea through the Egyptian military that no how, no way, do they want to get into a fight with the US military.
To the point that if some politicians suggests it, he is far more expendable than they are.
But it also means that he is an ice cold realist, and does not want his country to go to hell in a hand basket.
Perhaps Egypt needs another Nasser.
On a pertinent historical note, Nasser survived an assassination attempt in 1954 — by the Muslim Brotherhood.
