Actually, always think twice before attacking a bigger enemy who has more firepower. That is the lesson that we should derive from this.
Japan was actually the weakest of the main players in ww2 - their industrial output was dwarfed.
Germany launching bold attacks made more sense than Japan.
Some estimates I came across:
Paul Kennedy, The Rise and Fall of the Great Powers (1987), "warmaking potential" for 1937:
US - 41.7%
Germany - 14.4%
USSR - 14.0%
UK - 10.2%
France - 4.2%
Japan - 3.5%
Italy - 2.5%
Steel production thousands of metric tons, 1937-38:
USA – 51,400
Germany – 23,300
USSR – 17,800
UK – 13,200
France – 7,901
Japan – 5,630
Italy – 2,323
