Plot hole: After Pussy Gallore's airplanes spray "Delta-9" onto Fort Knox and the soldiers fake the effects, why does the army let Goldfinger and his nuclear device so far into Fort Knox? Wouldn't it be much safer to intercept him somewhere at the fence? He would be surrounded by thousand of soldiers either way, but without having the opportunity to plant his nuclear device in the building. The army even awaits the signals that the device is armed.Goekhan

While we later find out that the soldiers were faking the effects, the too-rapid response should have raised the bad guys' suspicions.
