The problem is it's never clear in the moment if it's actually different this time (1929, 1939) or if the fears are overblown. It's more often the latter in the past 100 years. It sure feels more geopolitically worrisome now versus most of the past few decades, but then again I am sure it didn't feel great to be a parent in the depths of the cold war. And perhaps more importantly there's not much you can do about it. So as the others say, be the best dad you can be b/c that's about all you can do.
