The Empire's Biggest MISTAKE! (Star Wars)

Theorists, we have not covered Star Wars in a WHILE. With the release of the Obi-Wan mini-series on Disney+,I knew it was time. Today, I want to figure out why the Empire REALLY lost the war against the Jedi and Rebellion. No, it's not the other side having moral high ground and Disney always having the good guys win. It's their ships. They SUCK!
