Global warming thaws the hill.
Disgusted with their living conditions and inflation caused by your wealth, your guard quits, you are tried under international law for crimes against humanity, and convicted.
Due to your inflation, U.S. dollars are next to worthless. I use Kenyan money to buy U.S. money, and then, under an agreement with the U.S. government, burn millions of bills and halt the U.S. mint for ten years.
I am now rich thanks to deflation.
I buy the hill.
My hill.
