When it comes to American foreign policy, the Constitution of the United States gives Congress a great deal of power. Only Congress can declare war. Spending bills — including appropriations for the military, for diplomatic activities, and for foreign aid — have to emanate from Congress. The War Powers Act further checks the ability of the US President to commit the country to armed conflict without a declaration of war.
When it comes to Congress’ role in American foreign policy, the Senate is the more critical of the two Houses.
In addition to sharing the above responsibilities with the House of Representatives, the Senate has the additional Constitutional power of “advice and consent” on Presidential nominees and the sole power to approve treaties. Over the next year, we can expect the confirmation hearings of new US Ambassadors to FYROM, to Turkey, and to Greece. This makes developments in the US Senate particularly critical for Greece.
