Sure, the Egyptian Army performed better than in 1967 - at first, when it had the initiative on the offensive. While Israeli losses were great, in the last stages they were not, and by the time of the cease-fire Egypt's ground-to-air missile installations had been destroyed and there was no Egyptian ground force to block the Israelis had they wished to advance to Cairo and its airfields - and if the Israelis had, how long could the war have lasted? How long could the Egyptian Army maintain its strength without supplies or external support, since all war materiel was Soviet-built?!
