Final answer:
The president has the formal power to negotiate executive agreements and provide humanitarian aid. The president can make use of informal powers to negotiate agreements and set the agenda for foreign policy. The president's actions are constitutional, but whether or not they are supported is subjective.
Step-by-step explanation:
a. The formal Constitutional powers that apply to this scenario are the president's power to negotiate executive agreements with foreign governments and the power to provide humanitarian aid. The president has the authority to negotiate agreements with foreign governments as part of their role in foreign policy. In this scenario, the president negotiated an agreement with North Korea to end its pursuit of nuclear weapons, in exchange for humanitarian aid and forgiveness of loans.
b. Informal powers and roles of the president that apply in this scenario include their power to make executive agreements and their role as the agenda-setter for foreign policy. The president can enter into executive agreements, which are pacts made with heads of foreign governments without requiring Senate approval. In this scenario, the president used this informal power to negotiate an agreement with North Korea. The president also sets the agenda for foreign policy and can take unilateral action in some instances.
c. The president's actions in this scenario are constitutional. The Constitution grants the president the power to negotiate agreements and make executive agreements. While treaties require Senate approval, the president can enter into executive agreements without Senate consent. In this scenario, the president consulted Congress but did not need to request a treaty.
d. Whether or not someone agrees with the president's decision is subjective. Some may argue that negotiating an agreement without Senate approval undermines the checks and balances of the Constitution, while others may support the president's use of executive agreements to take swift action in foreign policy matters.
