I can't image any Egyptian regime, no matter how fundamental, would mess with the crown jewels of their heritage. It would be a very short lived regime.
I agree. They wouldn't be messing with just the crown jewels. They'd be messing with the archaeological expeditions that take place, and the tourist industry. Egypt relies on other countries to invest and conduct the expeditions that have uncovered a lot of their antiquities. They also rely on tourists to keep their economy going. They wouldn't let either of those go without a fight.
