Both the Democratic and Republican Parties would support the idea that the United States should defend itself both in times of war and when it feels as though it's being threatened, since both parties believe deeply in national security.
To make it more reasonable is the answer to this question
They establish an empire by making colonies to increase wealth and power
True they were not able to keep up with things
Farming/ slavery.
This answer really depends on what the question is asking, the southern economy banked heavily off of farming, BUT it was impossible to provide and have such an abundance of crops without slavery. So, it depends on the options you have.
Hope this helps, man!
