If Egypt wanted to roll tanks into Israel, there are 2 major roads they could use as supply lines. The Gaza strip flanks one of them.

Given that Israel's allies are invading all countries that could get in the way of Israel's attacking Iran, either through direct military intervention as in Iraq, Syria and Libya, corrupting the government as in Lebanon, Kuwait, Turkey, and Saudi Arabia, or inciting social unrest as in Jordan (and Iran*). . . Egypt has plenty of reasons to hold onto every tactical edge it can grasp. The longer they, and the rest of the world, wait to end Israeli barbarism, the worse the conflict will be when it does happen.


*It's interesting how Iran has a huge heroin problem while American's are sitting on the largest source of heroin in the world in Afghanistan (heroin is made from opium, which is just about the only thing being produced in Afghanistan these days). At the same time Afghan opium is getting processed into heroin and smuggled into Iran, American hospitals are going though a morphine shortage (morphine is also made from opium).
