Although the separation of foreign policy powers between Congress and the president is defined in the Constitution, it appears that the president has the highest authority . Although the power to declare war rests with Congress, the underlying power the president has to send troops anywhere in the country without congressional approval has proven more authoritarian than the powers available the Congress. This is not to say that Congress is completely uninvolved in foreign policy, but Congress plays its role when the president acts and proposes something that would not suit citizens or other countries. This was attempted through the War Powers Act, but it ultimately did not constrain the president, but rather allowed him to find loopholes so he could still send troops without Congressional approval. In the end, it is always the President who has the most authority since he is the one who controls the troops and can direct them as he wishes. This is why I think the president holds more power in foreign policy than the president.
