American foreign policy has, since it has had any kind of military power (read about Pres Teddy), existed to promote, secure, and expand American business and the rich, abundant Am. way of life. USA has routinely destabilized govts, oppressed and exploited other nations’ peoples, and stolen all the natural resources they could. This has come covertly and overtly, as well, with regional wars and assassinations of uncooperative foreign leaders.

However, with its recent Second Great Depression, usa is in a bind to finance this world-wide forceful domination. Too its elite has gone international and cares little about usa unless it may do its bidding on a case by case basis. USA will be lucky if it can somehow slide into a British soft decline, but there is no nation around to give usa a pleasant landing spot.
American ideals have never existed in practice and are used as an excuse to bomb yet another hell hole around the world that has something the bribe-dispensing rich want to own. Its days are numbered.
