Saudi Arabia signed the Declaration of the Rights of a Child.
The USA did not.
The USA accepted two optional clauses but did not accept the main declaration.
According to UN glossary:
” 23. Signature Subject to Ratification, Acceptance or Approval
Where the signature is subject to ratification, acceptance or approval, the signature does not establish the consent to be bound. However, it is a means of authentication and expresses the willingness of the signatory state to continue the treaty-making process. The signature qualifies the signatory state to proceed to ratification, acceptance or approval. It also creates an obligation to refrain, in good faith, from acts that would defeat the object and the purpose of the treaty.”
In short, they agree with the spirit of it but aren’t willing to commit to it entirely.
In short, the USA and Somalia aren’t bound by it. Saudi Arabia and the other 194 countries ARE bound by it.
I know of a few examples. One is the working conditions in McDonalds in the USA go against the UN Declaration on the rights of a child. Also, we allow children to work in family restaurants around hot grease and such. Dangerous conditions in the rest of the world for a minor. Acceptable in the USA.
The USA is behind on this one… and on a bunch of them. A lot of them.
Also, executing minors is commonly practiced in the USA.
But, since the USA isn’t bound the way Saudi Arabia is, we can get away with it.
