A shortage of crops/food would have killed off the soldiers mostly, devastating the southern states. I hope this helped!
Thanks!

They started the korean war to prevent the spread of communism cause they associated communism with Russia. They did not like Russia .
"The Cuban Missile Crisis was Russia getting ballsy and really mad at us (Likely due to us having missiles in Turkey that could hit them)
And the Vietnam War was started for the same reason as the Korean War"
Simple. The Columbian Exchange exchanged diseased, people, plants, food, and animals. The Americas adapted with new plants and animals like cattle, chicken, etc., and more slaves. Europe gained potatoes, tomatoes, corn, squash, punpkin, etc.
New societies could depend on new sources of food, new animals. That also improved their local economy, and knowledge (learning)
The US<span> and the </span>Soviet Union<span> were only </span>allies<span> in </span>WWII<span> because they were both so worried about Nazi Germany. It was not as if the two countries had any natural reason to be </span>allies<span>. That means that we should not be surprised that they went back to being rivals after </span>WWII<span>. </span>
