Sure, and she's exceptional. I'm sure there are a few like Mrs. Thatcher that could make good sound decisions about war, etc. but IMO they are extremely rare. It just doesn't come natural to the majority of women. Of course there is Hillary. Hillary would make a great dictator!
Women have their place in the military too, but not on the front lines. I can't help but feel that most men would spend too much time protecting the women than they would fighting and protecting themselves. If I had a son it would terrify me to know he had a twenty something female watching his back. I do have a 30 year old daughter and I can't imagine her fighting among men. Maybe I'm just too old-fashioned. :-)
Israeli women are on the front lines and always have been. Other nations could be included in a list, beginning with the Israelis.
