Brave young men, in the prime of their lives going to War.....?

They may be attempting to try this already with the breakup of traditional family unit. They definitely already did it in the 1930's in Nazi Germany. Kids had gotten brainwashed so much they were informing on their own parents or anyone else who disagreed with Hitler. I don't think it would work here in the UK and other western countries as much as they may try. Unless of course you're talking about robotic soldiers and unmanned military craft.
