Passive is the right answer----Apex
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"
Hey there!
Your question is:
How did the United States benefit from its victory in the War of 1812?
My answer to this question would be:
The War of 1812 basically gave the US its true independence. The "Treaty Of Ghent" healed the relationship between America and Britain and gave the Americans a great sense of pride. This high level of pride led to the Western expansion and the building of a very strong army. This helped America become the most powerful country in the world.
Hope this helped, and as always,
Stay Crazy!!! :D
