When men see photos of a beautiful women or see an attractive woman in real life they become braver and greater risktaker. It also seems that seeing an attractive woman may make men more likely to support a war.
Chang showed men pictures of women and tested for statistically significant effects of those pictures on men’s attitudes about war and on their cognitive processes related to war. As he and his colleagues describe in the online March 23 Personality and Social Psychology Bulletin, they asked the men to rate their agreement with war-supporting statements. Men’s responses demonstrated a positive, significant statistical correlation between seeing photographs of attractive faces and endorsing war-supporting statements. This correlation was not demonstrated for photographs of unattractive women’s faces.

I don`t think there is many political conclusions that can be drawn from this, expect that this may be an extra reason to have a fair share of women in leading military and foreign policy positions. Women´s attitudes towards war are not influenced by looking at attractive men the reseach shows.
