How much of the number you site is arms and war stuff?
As of 2020 manufactured goods are just slightly below that of mineral export, ff that 20,8% is rolled steel, 17,7% are weapons and machinery, 17,3% is food, 16% are chemicals.
17,7% include weapons but I think industrial machinery and automobiles are more by volume.
As for trend I don’t get you. Look at half of Europe and Japan, some lost 40% of population since the end of Cold War.
Remove immigrants from US and it would look worse than Russia.
