The us strategy for winning the war of 1812 was the invasion of what?

The correct answer is:

A greater divide within the nation.

The Treaty of Amity, Commerce, and Navigation, Between His Britannic Majesty and the United States of America, was a treaty between the United States and Great Britain that averted war, resolved issues remaining since the Treaty of Paris of 1783.

It angered France and bitterly divided Americans, inflaming the new growth of two opposing parties in every state, the pro-Treaty Federalists and the anti-Treaty Democratic-Republicans.
