A globalist tries to control the business of the world. A liberal tries to control the government of the world. A globalist already owns a liberal so government is of no concern to him anymore. His enemy is competition. And his liberal governments job is to crush competition. A protectionist is a globalist with a small globe. Otherwise they are the same. An isolationist is the guy who seems to always get stuck with the bill. That's why he doesn't like expensive crowds.
