How would this compare to WW2 adjusted for inflation?
Based on
http://www.westegg.com/inflation/ (which cites Consumer Price Index statistics from Historical Statistics of the United States and the annual editions of Statistical Abstracts of the United States for inflation conversion)
and
http://the.honoluluadvertiser.com/peaceinthepacific/numbers (which cites the National D-Day museum for war costs),
I calculate that 3 trillion in 2010 dollars is about 86% of what was spent by the US to fight WWII (converting the 2010 dollars to 1945 dollars).
Adusted for inflation, I don’t know how it compares to WWII, but I can think of a stark comparison to John Brown with a thousand spears and a few carbines pulled off abolition.
We could have paid the Chi Coms back three times.
