ELI5:Why has the USA not ratified the UN Convention on the Rights of the Child?

Originally, because it forbade both the death penalty and life imprisonment for children. The constitutionality of these punishments for children was not conclusively decided until 2005 and 2012 respectively.

It also contradicts US adoption laws in many states.

Note that many countries that have adopted regularly violate it, so its practicality is not certain.
