Final answer:
The War of 1812 exposed three main problems for the United States: a weak military, a lack of financial resources, and inadequate infrastructure.
Step-by-step explanation:
The three problems that were exposed during the War of 1812 were:
- A weak military: The United States lacked a strong military to protect its trade, which made it vulnerable to attacks from other nations.
- A lack of financial resources: The absence of a national bank meant that the US had difficulty borrowing money to finance the war.
- Inadequate infrastructure: The country lacked proper infrastructure, such as roads and canals, which hindered the movement of the army and supplies.
