Was the men fault for?

for example all the wars through history,it always been leaded and fought by men's,in the rare cases when womens we're also involved but mostly I think it was done sole by mens and other stuff just as bad also made by men,for example a girl that gets pregnant by mistake she cant get pregnant by mistake without a man that does it therefore its the man mistake and I could go on,what i'm trying to say that most stupid stuff through history we're made by mens.
