Humans essentially all think the same way. Human kind will generally react the same way in general situations no matter what the sex. In my opinion, wars would ultimately end up the same over any given period of time. The reason for this is that while men are more prone to being power hungry, women are prone to lean towards their emotional side more. This would create many of the same war, if for different reasons.
This is a great topic to think about I believe I have the answer figured out. There would be the same or even more wars because its all in the human race and not in gender.

It might be that there would be more wars, but they would not be fighting with weapons, instead it will be a verbal warfare with economic sanctions all the time. It would be a mess
