Yup! It’s commentary on United States politics. There’s clear parallels here to Operation Paperclip. Ever since the new canon started Leia formed her Resistance because the New Republic just wouldn’t properly condemn/go against the growing Imperial remnants. This is like when Lucas compared the Empire to the United States – even though they had gone against the biggest empire in the world and won, they are now too unfortunately similar to them. Of course the New Republic is better than the Empire but the upper class in Coruscant and the working class in the Outer Rim haven’t been made to notice. Nothing substantial has changed about their lives. The status quo is too strong. The New Republic hasn’t done enough to rid the galaxy of the Empire. Things aren’t improving enough.
It’s one of the great things from the books set in this era that I am so glad to see be properly adapted into the shows.
