It looks like it goes in cycles: after major catastrophic event subsequent generations that don't remember the catastrophe are willing to engage in another one (I think of WWI and WWII as one event). If the memory was stronger there would be more pressure to find other means of resolving issues.
Eg. as a "half boomer" European I remember well why EU was created. It looks like the reasons have been largely forgotten now.
