Original link: Allies surpassed the US in military budget purchasing power last year, new report shows / DefenseNews.
The NATO allies are at 81% of US defense spending and the AsiaPac allies are at 30% of US defense spending.
Calculated as purchasing power ( US defense spending is still bigger nominal).
And in case someone wonder about the difference. Nominal means converting spending from local currency to USD using actual currency rate. Purchasing power means converting spending from local currency to goods at local prices. The difference in result comes from the fact that in some of the US allies the price of goods are lower.
None of the measures are inherently more correct than the other. Simplified then nominal reflect how many guns the country can buy while purchasing power reflect how many breads the citizens of the country have to give up to buy guns.
