The Gun Nut has published a letter from Fred Thompson, actor and presidential candidate. It is worth reading:

Last year, the United Nations Sub-Commission on the Promotion and Protection of Human Rights declared that international human rights law requires all nations to adopt strict gun control laws. These “minimum” provisions are much more restrictive than any of those on the books anywhere in the U.S. and would almost certainly violate the Second Amendment of our Constitution.

Besides concluding that all nations are obligated under international human rights law to control the small arms and light weapons to which its civilian population has access, the UN report remarkably denied the existence of any human right to self-defense, evidently overlooking the work of Hugo Grotius, the 17th century scholar credited as the founder of international law, who wrote, “It is to be observed that [the] Right of Self-Defence, arises directly and immediately from the Care of our own Preservation, which Nature recommends to every one. . . ,” and that this right is so primary, that it cannot be denied on the basis that it is not “expressly set forth.”
