A popular bumper sticker attributes to Albert Einstein the quote "You cannot simultaneously prepare for and prevent war." I must regrettably disagree. A society may be the most peace loving group of people in history, but that has absolutely no bearing on whether or not there is a despot somewhere ready to try to take it away from you. If you do not prepare to be rough if needed, you will surely get the chance to try it out. Being strong is not the same as being aggressive.
