Why won't the USA sign treaties? It would interfere with USA’s sovereignty.

If the USA is so keen on countries working together and pooling sovereignty, armies and foreign policy, here is a few questions for the USA leader when he touches down on UK soil.

• Why is the USA not signing the U.N.'s global arms treaty?
• Why won't the USA ratify the UN convention on children's rights?  (The USA is one of only three countries not to have signed the Convention on the Rights of the Child. The others?  South Sudan (which only became a country in 2011) and Somalia, which barely has a functioning government.)
• Or how about the UN Convention on the Law of the Sea?
• Or the Convention on the Elimination of All Forms of Discrimination against Women (CEDAW)? (The only other countries not to have ratified are Somalia, South Sudan, Sudan, Iran and the two South Pacific islands of Palau and Tonga).
• Perhaps ask about The Convention against Enforced Disappearance which prohibits the secret detention and abduction of people by the state? Awkward one that.
• If you have time would you like to ask about the non-ratification of the Mine Ban Treaty, the Convention on Cluster Munitions?
• Or the Convention on the Rights of Persons with Disabilities (CRPD)?

And this is just the start of the list!

The biggest barrier to the USA signing these treaties are fears that they will interfere with the USA’s sovereignty.  

All rather amusing given Mr Obama will be coming here to tell us to concede sovereignty to others.
