Israel will first use small neutron weapons. These will neutralize all the tank crews and the end result will be Israel inheriting 1000 M1A1 tanks. They will quickly establish air superiority and the Egyptian F16 fleet will be hidden as best the Egyptians can as they won’t want to lose them all.
The biggest danger is the massive missile barrage that would come in from all points against Israeli cities. If just one causes massive loss of life or if just one is not conventional then Israel will loose the big nukes against Syria, Lebanon, Egypt and Iran. Worldwide economic collapse would soon follow, it would make the great depression look like the good old days.
I just hope if it happens they nuke Mecca too.
