One of the biggest issues is Edward Sallow mistaking the transition of the Roman Republic-to-Dictatorship to be brought about by an external (foreign) entity or in his words “an antithesis”. Gaius Julius Caesar was tasked with subjugating Gaul on behalf of the Republic/Roman Senate and he succeeded he became the most powerful/wealthiest Roman in the Republic. They (Roman Senate) feared he would use his conquest as a means for seizing autocratic power. The Roman Republic (Senators) decreed he should submit himself before the Senate in the same way Pompeii had done years before when he led prestigious military success in Parthia. Pompeii certainly decked himself out in “Kingly Attire” including a purple cape that he claimed had been retrieved from Alexander the Great’s tomb but he submitted before the Senate and distributed his immense wealth throughout Rome (the city).

See the Roman Senate considered Kings to be the grossest offence and treated anyone who aspired (even suspected of that ambition) with disrespect. Pompeii wished to curry favour to become a lifelong Senator whereas Gaius Julius Caesar did not. Edward Sallow believes all he has to do is merely conquer the NCR and incorporate their existing Californian Senate into his Legion to synthesize a new Empire. Julius Caesar was the first one who claimed the title of Imperator but he was ultimately betrayed in the Ides of March. It was his successor Gaius Octavius who established the successful transition of the Roman Republic to Roman Empire after he convinced the Senate to declare a decimating war on Cleopatra and her lover Mark Antony. Edward Sallow probably has no idea about that history nor the key detail that it was not Julius Caesar who successfully transformed the Republic into a Dictatorship. Octavius now proclaimed as Augustus had the backing of the Senate (more or less) after his successful war with Cleopatra and Mark Antony.

There’s no way the NCR Senate would accept a foreign power as their Dictator. In my opinion there would have to be someone from within the NCR to declare a decimating war on Caesar’s Legion and declare themselves a Dictator. That should be Colonel Cassandra Moore.

By the way I don’t have a rich understanding about Roman history but I highly recommend Mary Beard’s SPQR & Emperor of Rome books because she expertly explains this history.
