I want to know the answer to the following question:
Any treaty provision that conflicts with the US Constitution is considered what under US law?
All the background I'm provided with is that "The Supreme Court ruled in the Head Money Cases that "treaties" do not have a privileged position over Acts of Congress and can be repealed or modified (for the purposes of U.S. law) by any subsequent Act of Congress, just like with any other regular law.". Is that enough to answer the question?
Answer: no
