I'm a guy, and I believe that history so far has been ruled by force. Rulers for example are the ones who rewrite history as they see fit, once they seize power.
However, society is fast becoming knowledge-centric. Knowledge is the new power, and that is the great equalizer for women. (If you wish, read Alvin Toffler's PowerShift for details on info-power).
9/11 for example was an illustration of how knowledge (or imagination) is more powerful than brute force or technology (which the U.S. has plenty of).
Finally, the fact that Commander-in-Chief, the new show starring the oh-so-sexy Gina Davis, is now a cultural fait accompli will only inspire more women to take on leadership roles in society.
Regardless of whether history proved or not that women were not as strong as men (due to cultural factors and the above mentioned centrality of brute force), history from now on will tend to favor knowledge as the new source of strength, whether you're a man or woman.
