Eastwood really has only two points he spends the movie dwelling on:
1. War is a brutal hell.
2. White people in the 40's were racists.
Some of the old war movie cliches are just too good for him to pass up too, for example, the senior officers are preening, incompetent boobs.
The ridiculous line that the country was going bankrupt or so weary of war that it was on the verge of offering the Japanese peace terms was laughable.
In those days, they didn't talk about post traumatic stress, which he DEFINITELY had. Contrary to public belief, he was NOT a problem drinker before they brought him back from the war for the Bond tour. He also was the first Indian to be in the elite Paramarines.
His is a fascinating story, so why Eastwood had to embellish it by adding something as far-fetched as that story is beyond me.
Also, the reason the first flag was taken down was because it was TOO SMALL. Not because some politician wanted it. Eastwood added that for effect. NEGATIVE effect. Pisses me off.
