America is the spawn of empire building and from the start has itself engaged heavily in that activity. In nearly all cases it has shown a preference for bribery, coercion, intimidation and force over diplomacy and cooperation.
As a nation founded on invasion, occupation and genocide, America has maintained its empire by those means to this day.
Throughout most of American history, the primary motivation for innumerable annexations, invasions, occupations, coups, assassinations and the installation of genocidal dictators has been to advance the agenda of capitalist globalization and to protect the privatized profit machine wherever footholds have been established.
Whatever the nature of the "business" that has entrenched itself in any sovereign nation, it can count upon the protection of its private security company; the U.S. government.
