So every single Nazi Youth true believer died before 1945? Not a single one survived in a hospital? Plenty of true Nazi believers survived the war in South America and elsewhere, often to be put on trial later. Many Nazi Youth were too young to fight in 1945.
Here you are tripping on your own double standards. You insist that not a single Nazi youth was not successfully rehabilitated in an earlier post, which I chose to not nit pick on, but that was a clearly impossible to back up claim, and now you are asking me to make a similar baseless sweeping argument?!
There have been cases of North Korean intelligence agents who were caught and brought to South Korea and, upon seeing the truth of a prosperous country, rejected their indoctrinated-since-birth beliefs about communism and capitalism.
When did South Korea launch North Korea-style cross boarder snatch and grabs?
It's telling that despite all the totalitarian regimes of the 20th century, none has produced the robotic killers you fear. War never wipes out all opponents. Nazi Germany and Japan took horrendous casualties and still some of their true believers survived, none of whom carried on the fight after 1945. The only ones who did were isolated Japanese soldiers are far-flung islands who gave up the fight once they returned to society.
You keep saying keeping that indoctrination of children since birth is unprecedented but totalitarian regimes have always done it and we have yet to see the "terror weapon in the truest sense of the word". If it's unprecedented, how can you be so sure it will happen? How can you be so sure education and socialization won't work?
Again, you are comparing apples to oranges. Not a single one of the regimes you described produced terrorists. They aimed to make the perfect soldier, who is very different from a terrorist, or just homicidal thugs in the case of African child soldiers.
For the perfect soldier, they were always trained and conditioned to act as part of a larger national state military organisation. They were never trained to fight independently behind enemy lines. They are like your soldier ants. Kill the queen and dismantle the hive and they loose their sense of purpose, direction and motivation.
In addition, all the modern historical examples of child soldiers were never raised from birth to be soldiers, but recruited in late childhood. That gives them a wellspring of positive childhood memories and experiences to help steer them back into a normal life.
It should also be noted that in all those historical cases, the 'perfect' soldiers were indoctrinated to either venerate a person or form of government. Both of those foundations could be sundered, and indeed, the death of the supreme leader and government they were raised to serve would have gone a massive way towards helping to rehabilitate them.
A terrorist is an entirely different beast. They are trained and raised to infiltrate enemy societies, resist 'temptation' and fight independently if necessary. Their perverted ideology is also incredibly hard to effectively counter and comprehensively dismantle.
Part of the reason why they are so dangerous is precisely because there are no valid historical comparisons, so there is no tried and tested template to use to counter them (other than kill them all, which is clearly not a remotely acceptable remedy).
The only remotely similar modern comparison would be Japanese soldiers in WWII who were fanatically loyal to their 'God-Emperor'. There are countless stories and examples of the fanatical, often suicidal zeal they fought with. Then, when their own Emperor demanded they surrender, a fair proportion of them chose suicide over obeying that order.
The Allies were projecting millions of casualties if they invaded the Japanese main islands, and the occupation would have been a living nightmare had the Japanese Emperor demanded his subjects fight and resist to the death.
That was a massive factor in why the 'unconditional' Japanese surrender was nowhere near as truly unconditional as the German surrender and why there wasn't anything like the systematic and thorough Nuremberg trials and purges afterwards to root out the die-hard true believes (another massive factor in explaining the comparative success in rooting out grown up Nazi-youth die hards which you entirely neglected to consider).
One only has to look at what the likes of ISIS has been able to do with western raised and educated adults, and the kind of monsters they moulded from those people to see the terrible potential of what they might be able to achieve with a 'clean slate' child that would have known nothing else and had no positive experiences and loving memories to draw upon to counter the poison the likes of ISIS would be filling their minds with.
There are many examples of terrorists who infiltrate western society, spending months or years living the kind of ordinary good life you suggest would make the scales fall from their eyes and rehabilitate them, yet they still held true to their perverted beliefs to launch or attempt to launch attacks or actively recruit people to join their cause.
In the case of African child soldiers, there was never really any ideological element to their abuse and training. It was enough that they fought and followed orders. There was no higher belief or justification beyond their actions other than because they were ordered to do it and because it was 'fun'. That, and their earlier normal childhood memories and experiences was fundamental in their eventual successful rehabilitation.
A trained from birth terrorist would have no such memories and experiences to draw upon, and they would have been trained from birth to resist 'temptation', almost certainly by western raised terrorist, who would teach those children to see hidden evil in every good gesture and act we do.
As I have said repeatedly, there are no applicable modern examples and comparisons. The only remotely appropriate examples are from ancient history. But I doubt the 'solutions' from those times (kill everyone, women, children and the livestock as well) is remotely palatable to any modern civilised society.
It may be possible to successfully rehabilitate individuals like that, but it will be orders of magnitude harder than anything else done before, and there will always be an element of risk and doubt in whether they are truly rehabilitated, or just employing part of their training to play along until they can slip under the radar and find an opportunity to strike.
It would only take one such case to totally discredit the entire rehabilitation effort and make people doubt every graduate of that programme.
Are you so categorically sure that any such rehabilitation programme could be 100% successful? If not, then that raises the terrible question of what you think we could and should do with people who seems to be rehabilitated? Do you assign resources to monitor them for life? What kind of restrictions would you put on where they can move to and what kind of jobs they can get? How would that kind of treatment affect their rehabilitation?
That is the most damaging weapon the terrorists have - they attack our best instincts and bring out the worst of us, and that is the biggest threat ISIS child soldiers will present to the civilised world - to push us to make impossible choices and deal with the awful consequences when they succeed in creating just one example of a truly un-redeemable innocent child terrorist.
You have the entire thing backwards. The burden, as with terrorist attacks, is not that they have to succeed in every single case, it just takes one to slip through to cause the damage and damn every other rescued child who was taken and trained as terrorists.
That is the kind of impossible moral choice they would force upon us - not that every single one of those child terrorists would be a die hard irredeemable monster, that would be comparatively easy for us to deal with. No, what happens when a small but not insignificant proportion of captured child terrorists are irredeemable but we cannot 100% reliably sort them from those who can be saved?
As with almost all terrorist attacks, the true damage is not from the attacks themselves, as bad as they can be, but from what the threat of attacks do to us, and how far that can push us from the morals, values and principles we hold dear and aspire to live up to in order to stop the terrorists and keep ourselves safe.
