From these arguments of the President it becomes apparent that the United States interprets Article III, No. 1, of the Hay-Pauncefote Treaty as stipulating no discrimination against _foreign_ nations, but as leaving it open to her to grant any privilege she likes to her own vessels. According to this interpretation, the rules for the use of the Canal are merely a basis of the neutrality which the United States was willing should be characteristic of the Canal, and are not intended to limit or hamper the United States in the exercise of her sovereign power in dealing with her own commerce or in using her own Canal in whatever manner she sees fit. The President specifically claims the right of the United States eventually to allow her own vessels to use the Canal without the payment of any tolls whatever, for the reason that foreign States could not be prevented from refunding to their vessels tolls levied upon them for the use of the Canal. If foreign States, but not the United States, had a right to do this--so the President argues--the irresistible conclusion would be that the United States, although she owns, controls, and has paid for the construction of the Canal, is restricted by the Hay-Pauncefote Treaty from aiding her own commerce in a way open to all other nations. Since the rules of the Hay-Pauncefote Treaty did not provide, as a condition for the privilege of the use of the Canal upon equal terms with other nations, that other nations desiring to build up a particular trade, involving the use of the Canal, should neither directly agree to pay the tolls nor refund to their vessels tolls levied, it is evident that the Hay-Pauncefote Treaty does not affect the right of the United States to refund tolls to her vessels, unless it is claimed that rules ensuring all nations against discrimination would authorise the United States to require that no foreign nation should grant to its shipping larger subsidies or more liberal inducements to use the Canal than were granted by any other nation. II. It cannot be denied that at the first glance the arguments of the United States appear to be somewhat convincing. On further consideration, however, one is struck by the fact that the whole argumentation starts from, and is based upon, an absolutely wrong presupposition, namely, that the United States is not in any way restricted by the Hay-Pauncefote Treaty with regard to the Panama Canal, but has granted to foreign nations the use of the Canal under a conditional most-favoured-nation clause.
