Which house of Congress primarily deals with foreign affairs?

The Senate primarily deals with foreign affairs for several key reasons. Firstly, the Senate has the exclusive authority to ratify treaties, which requires a two-thirds majority vote. This power underscores the Senate's role in shaping and approving foreign policy decisions.

Additionally, the Senate conducts confirmation hearings for ambassadors and other high-ranking officials in the State Department who are responsible for foreign relations. By scrutinizing these appointments, the Senate ensures that individuals representing the United States in other countries have the appropriate qualifications and align with strategic interests.

Moreover, members of the Senate often engage in foreign affairs discussions and activities, providing insight and advice on international relations. This involvement is crucial for maintaining a balanced and informed approach to the nation's foreign policy.

In contrast, the House of Representatives, while it can influence foreign policy through its legislative powers and budgeting, does not hold the same level of responsibility for treaty ratification or confirmations of key diplomatic appointments. Thus, the structure and powers granted to the Senate make it the principal body for dealing with foreign affairs.
