Well you are homogametic and therefore common sense is naturally expressed in your makeup. Unfortunately the world is largely ran by people with a common genetic defect - theyre heterogametic. This typically stunts their level reasoning so that it doesnt develop beyond the schoolyard level ;-)
On a serious note though the powers that make the decisions about going to war can rarely see anything beyond their own noses - they simply are happy to wade in with their guns blazing without any thought given to what happens afterwards.
