Dave says, We Are All Good Germans Now, and I get his point but while he is using metaphor, there is an actual act made by the United States for which we all Americans should feel is our birthright shame. The United States is the only nation on earth to drop a nuclear weapon on another nation, and this reality, which is our shame, is how most of the world sees us. Consider the reason why you never hear U.S. politicians suggest attacking North Korea.
Ever since World War II U.S. citizens have been told to fear the possibility of other countries dropping nuclear weapons on us, while the rest of the world knows the U.S. has and thus is willing to drop nuclear weapons on them.
