Time-frames. You imply major changes in geopolitics which typically need multiples of 100s of years. No body can plan for that long a period - they can sure pretend to. Such changes, often come undetected until we are well into or past them, so useful for anthropoligists and historians. Another example of a still larger time-frame are geographical and ecological changes (multiples of 10,000 years) IMHO, the GP's argument is relevant to time-frame of politics/policies in a few years/decades. Post 2nd world war and more so end of cold war era. Its US which rules the world, and so GP is quite right (found the Tyson example, hilarious).
