Carter feels that the stupid arrogant American people escaped without finishing their punishment. His whole presidency was dedicated to putting America in its place and making Americans learn what it is to suffer like the rest of the world.
When he got fired by the American people, it just fueled his pathological resolve to make them learn; to make them take their due punishment.
Carter has dedicated his life to the premise that no one has the right to be too successful or too comfortable. That is why he loves despots and tyrants. Because, unlike America, they keep their people 'in-line'.
Agree....excellent assessment!!
