Coral Bell writes that Australian Opposition leader Kevin Rudd's foreign policy approach is not likely to do serious damage to the relationship with Washington, but the alliance might be challenged within the foreseeable future by quite a different factor in world politics. The next landscape of world politics, she argues, which might be with us as early as 2010, will see six great powers share a central balance of power. And even perhaps a Concert of Powers. US strategic priorities will certainly continue to evolve, in line with the changing balance of power in the world. There does not seem to be much in that picture to threaten Australian security.
