@harrymccracken Not even close. December 7, 1941 should rank 1st, today pales by comparison. Plus two powerful regimes wanted to destroy the US & we were yet to devise a way to prevent that from happening.
@harrymccracken The 1960’s were traumatic on many levels…as were the Great Depression & WWII years. If we factor in #ClimateCrisis, however, your ranking may be correct.
