Obey the Constitution of the United States and work with the Senate in a treaty with Iran

Without Senate ratification, a deal between the United States and Iran is unlikely to outlast the current president.
This letter perfectly showcases the intelligence beneath our constitutional design. For America’s founders, both the Senate and the presidency are to channel and accentuate the best qualities of each institution, while preventing either from acting alone, especially in foreign policy. Each institution has its own distinct character and limitation—and each compliments the other.
