Can ANY glass window withstand a powerful hurricane?

Yes, absolutely. The trick with impact windows is that they sandwich a plastic polymer layer between two panes of glass. The window then undergoes the same small and large missile tests that Miami-Dade codes require for hurricane shutter panels. The large missile is an 8' 2x4 lumber shot out of an air cannon. The glass may crack/shatter, but the polymer layer ensures the building envelope is maintained, even against the wind pressure.
