History lesson:
In 1864 Paraguay fought against Brazil, Argentina and Uruguay, and was overwhelmingly defeated in 1870 after five years of the bloodiest war in South America. William D. Rubinstein wrote: "The normal estimate is that of a Paraguayan population of somewhere between 450,000 and 900,000, only 220,000 survived the war, of whom only 28,000 were adult males." Paraguay also suffered extensive territorial losses to Brazil and Argentina.
Next question?
This doesn’t explain why they bothered to invade.
There is virtually nothing there.
Paraguay for their size are badassed and heroic and understand full well victory and despair
Not to be underestimated
