In search of US strategic frontline

The question here is where is the United States' strategic "frontline". And by "frontline" I mean the focus of its foreign affairs.

Looking at the 2006 US military and diplomatic focuses separately, there were far more problems as well as interesting developments in the Bush administration's diplomatic undertakings than in its military affairs. Concerning its military actions, the "frontline" is, of course, still in Iraq, where more than 100,000 US troops are fighting the "war on terror" under the watchful eye of American television networks and other media.

In foreign affairs, the focus has been on the nuclear crises in Iran and the Democratic People's Republic of Korea (DPRK). But the first three "battles" were fought without a clear road map, making it hard to predict who will win, despite strong showings by the parties involved.
