It was nice while it lasted

It was nice while it lasted.

Thomas Jefferson, wrote "Millions for defense. Not one cent for tribute." He was speaking about Arabs holding Americans hostage for money and submission. His successor, one Barak Obama, now bows before an Arab potentate. Hope and change, baby. Hope and change.

I do have a highly technical constitutional law question for AT's reader/scholars: Does Congress have to vote to approve a surrender of the United State's sovereignty to a foreign power? And, if so, will a simple majority do, or will it have to have a two-thirds vote?

Thank you.
