Unresolved issues from the American Revolution continued to bedevil relationships with Great Britain, such as border disputes, the presence of a large body of “redcoats” on the margins of the Ohio territory, and impressment of sailors.

And was there a careful consideration of the costs of war (likelihood of success) that demonstrates sagacity and temperance rather than American hubris?
