I think it's simpler than that. The mindset you are describing is one that I think was only ever confined to a few intellectuals - people who would be conscientious objectors or anti-nuclear. It is good that they have found an answer to their own dilemma but I don't think it was ever much of a dilemma for the wider population.

For the bulk of the population I think the difference is firstly the war in Afghanistan, which has brought home the realities over a sustained period in a way that the short term conflicts of the previous few decades never did. And secondly the fact that with social breakdown the armed forces, instead of being seen as one of the roughest elements in society, are now seen as those with the greatest self-discipline and dedication. Qualities which are greatly admired in the current climate.

There is also the fact that they are one of the very few institutions left that people trust and respect.
