North America contains Canada, the United States of America (excluding Hawaii, which is in the Pacific Ocean) Mexico, Greenland, the Caribbean islands. It is followed by Central America down to the Panama Canal. Some, however, prefer to lump Greenland in with Europe and Central America in with South America). North America also technically includes the bit of Iceland west of the Mid-Atlantic Ridge, though Icelanders are culturally and economically European.
In addition to being NATO member states, the United States and Canada jointly host the North American Air Defense (NORAD) command, which remains active till this day.
There is a plot afoot[note 1] 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."
Central America is the part of North America south of Mexico. A good way to remember this is that it's the region between Mexico and Colombia. Its members are Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. The reason this term exists is because the former six countries were part of the Federal Republic of Central America, which failed miserably after, just like Gran Colombia, everybody started getting pissed off at each other and seceding. The reason Panama is part of it is because of when the US made it a de facto colony, before which it was considered part of South America. Costa Rica is famous for being the largest country in the world that doesn't have a military. Most of these countries are quite repressive and in poverty, and the average person makes $8,698 in purchasing power parity a year, which isn't too bad.
