Defensive Posture

I found this in the StratFor.com free newsletter. The topic itself was Ballistic Missile Defense but this brief retrospective view provides some interesting perspective.

The second idea dovetails with long-standing U.S. strategic doctrine -- a philosophy that long predates the Cold War. That doctrine has always aimed to push threats away from the continental United States -- initially by securing U.S. sovereignty over the North American land mass, achieving strategic depth and controlling sea approaches. Ultimately, the doctrine calls for the United States to project power into Eurasia itself, establishing as much stand-off distance as possible. In the early 20th century, naval power allowed the United States to do this just fine. But in the early 21st century, with the proliferation of intercontinental ballistic missile technology, naval power is only one leg of such a strategy.
