“There is nothing new or unique about what we say here. This Court has regularly and uniformly recognized the supremacy of the Constitution over a treaty. [Footnote 33] For example, in Geofroy v. Riggs, 133 U. S. 258, 133 U. S. 267, it declared:
“The treaty power, as expressed in the Constitution, is in terms unlimited except by those restraints which are found in that instrument against the action of the government or of its departments, and those arising from the nature of the government itself and of that of the States. It would not be contended that it extends so far as to authorize what the Constitution forbids, or a change in the character of the government, or in that of one of the States, or a cession of any portion of the territory of the latter, without its consent.”
Be Vigil For The Attempt to Have the UN Arms Treaty Ratified Before Obama is Cleared Out of the White House.
In 2013, John Kerry Signed UN Arms Treaty — saying:
“On behalf of President Obama and the United States of America, I am very pleased to have signed this treaty here today. I signed it because President Obama knows that from decades of efforts that at any time that we work with — cooperatively to address the illicit trade in conventional weapons, we make the world a safer place. And this treaty is a significant step in that effort.”
He also said:
“This is about keeping weapons out of the hands of terrorists and rogue actors. This is about reducing the risk of international transfers of conventional arms that will be used to carry out the world’s worst crimes. This is about keeping Americans safe and keeping America strong,” he said. “This treaty will not diminish anyone’s freedom. In fact, the treaty recognizes the freedom of both individuals and states to obtain, possess, and use arms for legitimate purposes.”
