For the first hundred years of American history, the United States was founded on the concept of a limited-government republic, one whose government did not intervene in the affairs of other nations, specifically in Europe and Asia. America's non-interventionist philosophy was summed up by John Quincy Adams' Fourth of July address to Congress in 1821, the title of which is "In Search of Monsters to Destroy."
Later generations of Americans abandoned that founding foreign-policy principle and adopted the opposite philosophy — interventionism. The big turn came in 1898 with the Spanish American War, continued with World War I and World War II, followed by the Korean War and Vietnam War, culminating in today's forever wars in the Middle East and Afghanistan, with coups, invasions, assassinations, kidnappings, and partnerships with and support of foreign dictators thrown into the mix.
Americans today have a choice: Restore America's founding principle of non-interventionism or continue embracing foreign interventionism.
