Marco's re-posting of my comments long-ago contrasting Australian and American democracy omits my conclusion, which was as follows:
From this I draw the conclusion that instead of trying to change our system with stupid constitutional referenda, we should be encouraging the US to adopt our system. We can pick Hawaii off pretty easily as state #7, and once we have taught them to play proper forms of football we can annex the West Coast as states #8,#9, #10, #11. We could get rid of the federation star and put a representation of Coma Berenices in the top right of the flag to represent the New Far Northern states. This will make more sense than building nuclear reactors in Australia, because they already have nuclear reactors in California.
I've pasted on the Ursa Major stars from the state flag of Alaska instead, conceding this is a more immediately recognisable Northern Hemisphere constellation, and can do double duty for the bear of the California Republic flag. The seven stars also replace the Federation star to symbolise the seven* states of Australia, while the five stars of the Southern Cross will also represent the five states of the Borealia part of the Federation.
* I have promoted the Northern Territory. Unfortunately, it will be necessary to relocate the Federal Capital to a more central location, such as Palmyra Atoll, so the current ACT will be resumed by New South Wales.
