>That reasoning is flawed, since neither Hitler nor Caesar orchestrated the war that allowed them to raise to power, also Palpatine is clearly a better stand in for such characters than Darth Vader, who is just an enforcer for such a person.
Does it matter in-universe whether the conditions the led to Palpatine's were his doing or some matter of external force? Neither the PT or the OT are meant to be straight allegories of real world events rather than being applicable to them while still being their own thing. While the Empire had influences from Germany in WW2, in reality it is quite different and that design cue is merely one of a series of ingredients to the recipe of Star Wars.
You can't even compare the Clone Wars or the GCW to the 20th century world wars anyway, as both were civil conflicts more closer to the American Civil War (the Clone Wars especially) than anything else.
>Meanwhile the Clone Wars as represented by the Prequels and accompanying media fails to be Anakin's Vietnam or any other war. I could accept if they tried to make him some type of Achilles character, but the Anakin the Prequels gave us is a less cartoonishly evil version of a Joffrey Baratheon.
I suggest you read the Jabiim arc of Star Wars: Republic if you want a war is hell story with Anakin at center stage. Anakin is meant to be a very troubled and flawed character, with his obsessive attachment to those he loves (his mother, Padme) leading him to be seduced by Sidious. It does not matter if he is likable as that is subjective-tier redditor swill that takes feelings as actual facts. What truly matters is that he is a CONSISTENT character and in the PT Anakin acts fairly consistent throughout. Anakin isn't "cartoonishly evil" at all, his flaws come from a very real and human place, which leads him to make a Faustian pact with Star Wars figurative devil figure. I think you are disappointed because you fell into the same trap many other Star Wars fans did and imagined Anakin as some PTSD-ridden Darth Rambo and got mad when it didn't match up to what was on-screen.
