What do you mean? There are small effects for the depression and WW2. I would argue that the nuclear threat and the cold war really only started to have a significant impact on the overall psyche of societies after the 70/80s. The peace movements really only started in the early 80s (except for the opposition to the Vietnam war which is actually reflected in the record). The 50/60s were generally characterised by an broad optimism and believe in the future (look at all the things they thought we could do). More generally you seem to dismiss the work largely because it does not match your preconceived notions of what should have been major effects. Maybe the question is to ask why they might not have. Or at least bring up evidence that they had a great impact on the language used.
