The difficulties the U.S. faced in preparing for war with Britain included:
- Britain had a much larger navy than the U.S.
- The U.S. had a small army compared to Britain.
The other options do not accurately reflect the historical context of difficulties the U.S. faced in preparing for the war with Britain (e.g., the mention of enslaved African Americans refusing to help fight is not applicable in this scenario). France was involved in earlier conflicts with Britain, but their direct support for the U.S. against Britain during the War of 1812 was limited.
