War and Love

I find the expressions of combat and love in literature and myth to be very similar in practice; both are topics that invoke emotion and promote passion in many people, while also being something most people pursue without fully understanding what it is or means. What's most interesting to me, however, is how historically they are mutually exclusive; I cannot name a time where we as a country have went to war out of the interest of the country we are at war with, and not because of fear or malice. It speaks a lot to us as a society, that in the absense of positive relations our thoughts immediately go to danger.
