What was one reson world war end?

Answer 1

Both wars have different reasons for ending.

WW1- Germany was slowly falling short of weapons and artillery. They'd been spending so much money on the war they were slowly growing bankrupt and were forced to surrender for the lives and money of their country and people.

WW2 - For similar reasons to WW1, Germany were running out of resorces and pushed themselves so far they had to surrender. The Atomic bomb actually ended WW2. The Japanese refused to stop, so in the end the USA dropped an Atomic bomb, which caused devistating birth defects and ruined a lot of famous places. The Japanese had no choice but to give in.
