Currently, international agreements are executed by executive agreement rather than treaties at a rate of 10:1. 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. For example, the deal by the United States, Iran and other countries is not a Treaty.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The president of the United States might prefer the formal treaty process for agreements that impose what type of legal obligations on the US?
Ah, so.. long-term, complex

Known as the world's automotive center, "Detroit" is a metonym for that industry. Detroit's auto industry, some of which was converted to wartime defense production, was an important element of the American "Arsenal of Democracy" supporting the Allied powers during World War II. It is an important source of popular music legacies celebrated by the city's two familiar nicknames, the Motor City and Motown. Other nicknames arose in the 20th century, including City of Champions, beginning in the 1930s for its successes in individual and team sport; The D; Hockeytown (a trademark owned by the city's NHL club, the Red Wings); Rock City (after the Kiss song "Detroit Rock City"); and The 313 (its telephone area code).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What "Arsenal" was Detroit a part of ?
Ah, so.. Arsenal of Democracy
