2 million children will be sexually exploited
Well, that is the reality but very few people care about that. The reason states do not do anything about this is because of the lack of resources.
Generally, the kidnapped children are taken away far from where they were born. So, the new areas care little about the "outsiders" or don't want to spend resources on it.
Very good point, a lack of resources is definitely a major factor. What interests me here is that the NCMEC is very well funded receiving millions from the US gov, they use cutting edge software created by Palantir but they cannot produce a comprehensive list of missing children.
