I think this is a fair point as well. Depending on women, PMS can have more or less impact. Some women can have suicidal feelings (I let you imagine what could happen in an airplane of the Air Force), can cry, can be angry. Others as far as I know can be relatively psychologically normal. However with hormonal control (e.g.: birth control pill), I have heard psychological side effects can be reduced to zero. I am not a doctor so please take this last statement with a grain of salt.

However birth control pills can/may have bad health impacts, so would it be worth it in order to work in the army or have political control? I am not sure (in my case I am against, but I think women should choose also for this). But in the end, men can also make bad decisions. I am always criticized for having no emotions at all, or for not caring at all, so in this respect women can bring balance. Being married in my case forces me to think more about others. Female and male apes together strong, hahaha.
