How did the war of 1812 contribute to Americas desire for isolation?

The War of 1812 heightened American nationalism and fostered a sense of unity, leading many to believe that the U.S. should prioritize its own interests and avoid entanglement in European conflicts. The war exposed vulnerabilities in American military and economic independence, prompting a desire to build a self-sufficient nation. As a result, the U.S. increasingly embraced isolationist policies to protect its sovereignty and avoid the political and military challenges associated with foreign alliances. This shift laid the groundwork for a long-standing trend of American isolationism in the 19th century.
