The Triumph of The Will is a quoted inspiration for that composition. The original source might send shivers up our spines but for patriotic Germans it may have felt good back then. Even the title A New Hope has fascistic undertones. Hitlerism plays with the same heroic language that mythology does. Star Wars is modern mythology.
None of that is Nazi imagery, trying to evoke feelings based on expressed association. The A New Hope shot posted above is not trying to instil audience feeling by conjuring up a known counterpart, particularly a beaten-do-death and low brow cheap fall-back one, such as Nazi imagery in serious fiction.
I’m not sure if English is your first language but that is what I said. The imagery used in the Throne Room scene is meant to evoke the original intent of the Triumph of the Will composition, that of heroism and triumph not the feelings associated with Nazism. The Imperial uniforms and Jack Boots and even to some extent Vader’s helmet is supposed to remind us of Nazis.
I’m all for associating Nazism with evil. I think culture needs a bit of a reminder now and then but bear in mind the Nazis themselves pinched from Ancient Rome and even more Ancient India for some of it’s iconography and so did the first order and movies about both.
