Went to war twice? Come on. The US has gone to war, or intervened militarily in another country’s governance with extreme prejudice, more than 50 times since World War II. Korea, Guatemala, Iran, Indonesia, Haiti, Vietnam, Cambodia, Laos, The Congo, Brazil, Peru, The Dominican Republic, Cuba, East Timor, Ghana, Uruguay, Chile, Bolivia, Grenada, Nicaragua, El Salvador. And much more. A country can’t “learn its lesson” when the people don’t even know their own military history and believe that something which has been happening for over a century is a new development.
