For the positive, see Finland, which is working hard to be a very well-prepared nation. Heavy buy-in from all across the populace. Exactly the kind of nation I was talking about - their survival depends on it. Poland, Sweden, Denmark all doing similar.
For the negative, see UK and US during COVID. The individualism that has underpinned society since Thatcher/Reagan as made us less likely be prepared, less likely to look out for our neighbour. Both are isolated by water, so we're naturally less bothered about invasion.
