The American Empire by Alan Caruba

The American Empire exists only because nations around the world continue to buy our treasury bills. Our debt. Awash in our dollars, they purchase our assets even though we tend not to notice or care unless it is Dubai and we get scared about “port security.” Never mind that communist China runs the largest U.S. port on the West Coast or that 80% of U.S. ports are foreign owned, primarily by shipping lines.
