It also gets quite a bit wrong. First, Gaius Julius Caesar said "alea iacta est". Secondly, he didn't introduce the Egyptian calendar, as his advisor Sosigenes had suggested. That calendar had 12 months of 30 days each, and a festive season of five days (each day dedicated to a god or goddess). Far more rational than the odd/even/February 28 botch that he perpetrated.
And yes, he gained power by force, while President Trump gained power by telling the truth. Big difference.
