I want to know the answer to the following question:
The president of the United States might prefer the formal treaty process for agreements that impose what type of legal obligations on the US?
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?
Answer: yes
