I am currently watching a series about World War 1 that was on one of the documentary channels a few weeks ago (I recorded it).
The opening couple of programs were about the build up to the war, and you do realise it was all about "power" and "success" and "might" and a certain amount of male posturing.
Male leaders in flashy gaudy uniforms, riding around on horseback and trying to prove their country was better and stronger than another country.
Germany jealous of Britian's Empire and wanting one of its own. Willing to go to war to destroy the British Empire (which in itelf was gained by power and might over often defencless nations).
"Empires" like Turkey, Russia, Austria/Hungary, Germany, Britain etc, all wanting to be bigger and more powerful than each other, and all driven by men.
So while I dont agree totally with Morrissey (who I have always thought of as a bit of a tw*t) he does have a point that almost all wars are started by men who want more power or position or money in their life.
