It's not the 1930s.
Victor Davis Hanson is concerned:
'But if America abrogates the preeminent leadership position it has held for the last 65 years, wouldnâ??t the world look a lot like it did in the pre-American days of the 1930s? Then, a Depression-era United States was just one of many powers, and was reluctant to assert leadership abroad.In other words, the post-American world could look a lot like the rather terrifying pre-American version of seven decades past. Why in the world would we wish to return to it?
'
The trouble with these kinds of formulations is that they're hopelessly vague - what, in specific terms, does it mean to "abrogate the preeminent leadership position" and why is this something we're concerned with at the moment? Then there's this:
'The so-called international community cared as much in the 1930s about rising, aggressive totalitarian states in Germany, Italy, Japan, and Russia as it does today about ascendant China or Iran. '
Obviously, things can go very badly abroad without having to rise to the level of Nazi Germany or the Soviet Union, but it behooves us to keep some perspective.
