Which country's total war spending was the highest at
the end of World War I?

Germany saw the largest spending after the Second World War. There were 110 000 000 soldiers deployed, there were 1773700 killed, 4216058 wounded, and total spending of 37775 000 dollars. Explanation: From 1914 to 1918, World War I was a major armed battle. 9 million soldiers were killed, 21 million wounded and 7 million handicapped.

Hope this helps.

this means that germany had to pay the allied countries. reparations are/is essentially payment for something that they have done wrong, so after ww1, germany was forced to pay reparations so they could replenish the allied countries resources' that they had lost during the war.

food chain i would say only because there is competition on getting food and survival
