Final answer:
Treaties are generally given preference over executive agreements as they carry more weight and require a more extensive process for approval. However, executive agreements can still be effective and have the advantage of being easier to negotiate and implement.
Step-by-step explanation:
Treaties and executive agreements are two different ways in which the United States enters into international agreements. A treaty is a formal agreement that requires approval from the Senate, while an executive agreement is made between the President and a foreign government without Senate approval.
In general, treaties are given preference over executive agreements, as they carry more weight and require a more extensive process for approval. Treaties are considered binding international law and are more difficult to reverse. However, executive agreements can still be effective and have the advantage of being easier to negotiate and implement.
For example, in the case of the Iran Nuclear Agreement, the President used an executive agreement to finalize the pact. This allowed for a faster resolution and implementation of the agreement. However, it also meant that the next President could potentially reverse the agreement more easily than if it was a treaty.
