Diplomacy.
Under Article II of the Constitution, the President is granted the power to deal with foreign affairs: this can be entering and discussing treaties, policy decisions, meetings with foreign heads of state, and executive agreements. However, treaties that the President enters into must be approved by Congress (2/3)--these are called congressional executive agreements, and they can be ex-ante or ex-post. Further, Congress can delegate certain elements of its own powers, such as law-making, if it is deemed to be closely connected with the President's goals of foreign policy.

The implied powers of the president in foreign policy making is the draft. Abraham Lincoln implemented the draft during the civil war.
One of US President Franklin D. Roosevelt's first foreign policy initiatives was to send a representative to Geneva Switzerland, to visit with the League of Nations. Roosevelt wanted to convey his positive response should there be any international arms reduction agreements. He also made it known if other peaceful nations had identified an aggressor nation and sought to used armed force against such a nation, the US would not impede the use of such armed force. This was a delicately worded policy statement to involve the US in any international peace agreements. Roosevelt was making this initiative without consulting the US Congress, and with the full knowledge of the US's reluctance to become involved at all in what he had suggested.
The President cannot unilaterally declare war without the consent of Congress. The President has to present evidence to Congress that a war would be necessary and legal. Thus Congress acts to check the President's power.

Answer this question… Making final decisions
The basic objective of any government's foreign policy is to further the interests of the nation it serves. With that said, foreign policy is geared to making sure the nation is secure militarily by forming military and trade agreements that produce wealth and help pay for the military. Foreign policy leaders negotiate with friendly and unfriendly world powers to ensure the aforementioned objectives.
The three main duties of a foreign policy leader are: 1) Protecting and promoting the country's national interests in the international arena; 2) Building and maintaining diplomatic relations with other countries; 3) Negotiating and making decisions on international issues, including trade agreements, alliances, and security arrangements.
