Mussolini planned tor restore the glory of the Roman Empire by taking over the neighboring lands.
Step-by-step explanation:
Mussolini used a rather strong argument for his own fascist and imperialistic tendencies by evoking Rome and its glorious empire of the past.
The insistence was that if the law of Mussolini was followed the people could realistically go back to the days of the roman empire, something that was quite improbable in the modern world.
He was willing to do this by expanding military might and by subjugating the other nations around Italy.
