Poor strategic decision making since 2001 has involved the United States in messy civil wars that will take years, if not decades, to resolve. In Afghanistan, Iraq, and Libya, regime change has come easily, but a limited commitment to stabilizing those nations has resulted in messy, bloody, and expensive aftermaths. Those wars show that military success alone cannot ensure a stable post-conflict outcome. Only the presence of US military forces, economic aid, and a long-term political commitment from US policy makers to rebuild and restore defeated nations can ensure enduring peace.
