The United States was losing public support for the Korean war so Truman
 and his advisors decided to work for a negotiated peace. MacArthur 
disagreed. The general believed that America's future lay in Asia, not 
Europe. In an inflammatory letter to the House minority leader, 
Republican Joseph J. Martin, he denounced the Korean stalemate, 
declaring "There is no substitute for victory". His strategy backfired 
and on April 11 Truman relieved MacArthur of his command, accusing him 
of insubordination.
