I think this is part of the motivation for adding a 51st state. Add a state and the flag has to be redesigned. And they’d push hard for a major redesign. It’s all part of the “cultural revolution” aspect of bringing this country down. Remove any connection to the past.
Who says?
When Alaska was added they did not redesign the flag. It was not redesigned until Hawaii was added.
The flag went from 48 to 50 stars.
