"War is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth fighting for is much worse. The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than he.
"People sleep peaceably in their beds at night only because rough men stand ready to do violence on their behalf."
Same concept applies. Some people take freedom as air; it comes with being alive. They've never known life without it, and they wouldn't know the first thing they'd do without it.
