North America is part of the vast American Supercontinent that is all that remains of Pangaea after Europe, Africa, China and India broke off during the Noahic Flood approx 4400 BC. Evolutionists claim that the first people to make it to the continent did so by 14,000 BCE after crossing a land bridge over the Bering Strait. It was originally "discovered," however, by one Christopher Columbus, although others may beg to differ.
The North bit of it contains Canada, the United States of America (including Alaska and Texas) and much of Mexico. And, although nobody cares, North America also includes Greenland, the Caribbean islands, all of Mexico, and Central America down to the Panama Canal (even though some people prefer to lump Greenland in with Europe and Central America in with South America). Hawaii on the other hand is not part of North America. It is an island that is in the Pacific and it is right here. Hawaii is in the Pacific. North America also technically includes the bit of Iceland west of the Mid-Atlantic Ridge, though Icelanders are culturally and economically European.
Much of America's (USA) defense forces focus on Canada and Mexico. There is no evidence to suggest that either country really cares, or that it's very effective.
There is a plot afoot to create a "North American Union", by merging Canada, Mexico, and the US together through a NAFTA Superhighway. The currency would be the Amero. Somehow, this is supposed to dilute the sovereignty of the United States, despite the fact that, as the most populous, richest, and most powerful part of this union, it would likely dominate it. Instead, it is somehow supposed to create a "socialist mega-state."
