Your reference to a society's "way of life" is significant here. Some aspects of culture become unimportant. Others become even more important than ever. In determining what aspects of a society's culture (or way of life) will be the most important, we should not look at what if fought
like in previous non-crisis wars. Rather, we should look at what it fought
for in previous-crisis wars. We should also look at what the perceived differences are between a society's own culture and its enemy's.
So for Americans, important cultural values fought for in previous crisis wars include: opposition of foreign rule, personal freedom, abolition of slavery, the English language (at least compared to German), and abhorrence of death camps. So as extreme examples, no mater how bad things get we will not see the United States swearing allegiance to the British Crown for protection, importing slaves to work its farms and supply its army, or extermination several million people in gas chambers. These things are simply anathema to the American way of life.
