The Russian economy is less than a tenth the size of the United States or the European Union
I wish I had the self-confidence to pontificate on Russian domestic arms production while apparently being unaware of something as basic as purchasing-power-parity adjusted measurements.
Right, I should make myself clearer. I’m no expert in economics, I just try to build a reasoning based on what I know.
The context of his statement is that Russia is outproducing the West in ammunition, specifically artillery shells. Earlier he states Russia is producing 4 millions shell a year compared to .5 for the US. So without qualification, the statement implies Russians are somehow 80x superior as they produce 8 times more with an economy a tenth the size.
I feel he should have qualified his statement to improve reader understanding:
Because he didn’t provide this context to the number he is giving, I thought that either he wanted to misled or he was not sufficiently informed, and assumed the more charitable option.
