Which is a responsibility of the Senate in regards to foreign policy?

By granting the Senate the sole power to offer advice and consent on nominations and treaties, the Constitution gives senators a major role in American foreign policy. Presidents nominate diplomats and negotiate treaties, but the Senate determines whether those nominees will serve or if those treaties will be ratified.
