I am saying if you remember something different from what Wikipedia has, check other sources and don't instantly assume you are wrong.
And I'm saying that this line of thinking, if that's the way you think, should not be specific to Wikipedia. I'm just tired of the instant distrust people have for the site. Besides, a good article on there will already
have links to their sources.
And I'm also saying that Bruno's confusion has nothing to do with Wikipedia at all, and whether it's right or wrong, but you seem to still be implying that.
In the show I know they've mentioned Korea a number of times so it's also not an issue of where he was. They haven't mentioned specifically that it was the Korean War that I recall - that's what prompted this whole line of thought. That and I thought I'd read the date 1944 on screen.
You are correct on all counts. I've specifically noted this while watching the show. I keep wondering why they never say "the Korean War," but then again I think it might be because they were so close to it. These days we say that someone was "in Iraq" or "in Afghanistan" for the most part. At that time, they probably also weren't saying "World War Two," but I really don't have any concrete knowledge of that. Perhaps if there were a Wikipedia article...
I think another question would be: which war did Roger Sterling fight in? We know it was an earlier war than Don's, and one that Sterling considers a "better" war. One problem is that I'm not sure how old Sterling is supposed to be (and his -possibly prematurely - gray hair doesn't help the guessing). But assuming he's maybe 45-50 in season 1, that would make him anywhere from 24-35 during the years of WWII. That seems slightly old. On the other hand, I don't seem him being in his mid-late 60's and having fought in WWI. Besides, he holds a distinct dislike for the Japanese...
So I really think it was the Korean War that Don fought in. I agree, though, that it doesn't make sense. Even if he was sent home early in the war, say 1951, like you said he worked in a car dealership, took night courses, lived with Anna for - I believe -two years, then worked in a fur shop, then worked in Sterling Cooper long enough to be the most important man there and seem very settled in. You're right, that seems to add up to far more than 7 to 9 years.
