What are the methods congress and the president can use to carry out American foreign policy?

Congress and the president employ various methods to implement American foreign policy. The president can negotiate treaties, appoint ambassadors, and direct diplomatic relations, while Congress holds the power to ratify treaties, regulate commerce with foreign nations, and allocate funding for foreign initiatives. Additionally, Congress can influence foreign policy through legislation, oversight, and the power to declare war. Both branches often collaborate, with the president taking the lead in diplomacy and Congress providing checks and balances.
