The United States, which in the negotiation got just about everything that it wanted, refused to sign the agreement that speaks to global Internet governance. Why? Because the United States does not want to recognize any shared governance of that which it largely controls, namely, the root domain servers that assigns names and numbers on the Internet. ICANN is an arm of the Department of Commerce, which is the government agency still in charge of those servers. The very process of this treaty poses a challenge to the United State's singular control over the technical foundation of the Internet as it operates internationally today.
