Fun fact: No one knows how percentage of GDP the Soviets were spending on their military, but 10% is the low estimate. (See second figure.)
The fifth figure should put to rest the idea that the Soviets tried to meet an increase in US military spending in the 80s. They didn’t. In fact, the president exact opposite is true. The US increased spending due to an increase by the Soviets in the mid 1970s. Soviet spending didn’t really increase at all in the 1980s.
I wonder if that was due to GDP falling with weak oil prices, or just rising military budget with a stagnant economy.
