The UN Arms Treaty is again, rising to the surface. The latest version was finalized this past March 2013.
It needs to be clearly understood that the United States does not need the UN. So one might reasonably ask, what is the purpose of America signing any of the UN-sponsored treaties?
When any country signs onto a UN treaty, that country effectively gives up a some sovereignty by placing itself under the auspices of the United Nations. In effect then, certain laws of a particular country could eventually become infringed or entirely canceled out because of that position.
