US and human rights

The United Nations inaugurated its new Human Rights Council on Monday, vowing to uphold the highest standards of human rights and erase the tarnished image of its predecessor. The 47-member council replaces the Human Rights Commission, which became discredited in recent years as rights-abusing countries conspired to escape condemnation

The new council will hold more meetings than the commission, comprising 10 weeks a year — greater than the current six weeks. It will also be easier to convene special sessions to respond quickly to human rights crises. Furthermore, any member that "commits gross and systematic violations of human rights" can be suspended from the council by a two-thirds vote of the General Assembly. Why do you suppose that the US did not campaign for a seat on the new council???????????
