I'm not sure that we should feel the need for this kind of imperialism in the 21st century. We can certainly "defend our borders" militarily, but wouldn't it be wise to make sure our economy can be sustained regardless of the actions of other countries? I think another take-away is that we should be transporting more goods by rail and water. The decline of our railways has helped the oil companies but has resulted in a huge number of truck-car deaths at the same time it's increased transportation costs. We should move more towards using trucking only for local deliveries.
