Claim: The Hay–Pauncefote Treaty provided that a canal might be constructed by the United States, or under its direction, which caused intense hostility in the U.S. to which Senator Henry G. Davis offered an  amendment.
Evidence: It provided (1) that a canal might be constructed by the United States, or under its direction, (2) that the canal should be permanently neutralized on the basis of the Suez Canal agreement — to be kept open at all times, either of war or peace, to all vessels, without discrimination, and no fortifications to be constructed commanding the canal or the waters adjacent, and (3) that other powers should be invited to join in this guaranty of neutrality. These provisions excited intense hostility in the U.S., and Senator Henry G. Davis offered an amendment adopted by the Committee on Foreign Affairs.
