"I would like to personally invite Australia, Canada, Greenland, Iceland and New Zealand, or any other English speaking country, to join the United States in forming a new nation."

The new proposed union of Ameristralia would consist of the follow:

So the total land mass would be about 12,339,567 square miles, or 23.5% of the total 197 million square miles on the planet.
Total population would be 395,669,994 out of about 7.7 billion people on the planet. This equates to about 5% of the total.
Total Gross Domestic Product (GDP) is $23,897 billion out of the planets GDP of 88 billion. Or about 27% of the total.
So Ammeristralia would have basically 25% of the land mass, 25% of the GSP while only having 5% of the population. The result would be a greater chance of Peace through Strength.
