I want to know the answer to the following question:
The international deal between the US, other countries, and what controversial nation is not a treaty?
All the background I'm provided with is that "Despite the relative ease of executive agreements, the President still often chooses to pursue the formal treaty process over an executive agreement in order to gain congressional support on matters that require the Congress to pass implementing legislation or appropriate funds, and those agreements that impose long-term, complex legal obligations on the United States.". Is that enough to answer the question?
