Me : Sit your kids down and say "I'm sorry for the hardship, famine, horrors, depravity and obscene inequality you will face. But we were the many and the few told us we could do nothing. Try not to let your kids down like we did to you."
Me : Try it. Sit your kids down and apologise then come and explain to me this is just excusing inaction. Don't tell me this until you've apologised to your kids first.
