Fifthly, when, in 1903, the United States by the Hay-Varilla Treaty, acquired from the Republic of Panama the strip of territory necessary for the construction, administration, and protection of the Canal, she acquired sovereign rights over this territory and the future Canal _subject to the antecedent restrictions imposed upon her by the Hay-Pauncefote Treaty_, for Article IV of the latter stipulates expressly that _no_ change of territorial sovereignty over the territory concerned shall affect the neutralisation or obligation of the parties _under the treaty_. These are the unshakable historical facts. The United States did not _first_ become the sovereign of the Canal territory and make the Canal, and _afterwards_ grant to foreign nations the privilege of using the Canal under certain conditions. No, she has never possessed the power of refusing to grant the use of the Canal to vessels of foreign nations on terms of entire equality, should she ever make the Canal. Free navigation through the Canal for vessels of all nations on terms of entire equality, provided these nations were ready to recognise the neutrality of the Canal, was stipulated by the Clayton-Bulwer Treaty, and this stipulation was essentially upheld by the Hay-Pauncefote Treaty, and it was not until two years after the conclusion of the Hay-Pauncefote Treaty that the United States acquired sovereign rights over the Canal territory and made preparations for the construction of the Canal. For this reason the contention of the United States that she has granted to foreign nations the use of the Canal under certain conditions and that such grant includes a conditional most-favoured-nation treatment, is absolutely baseless and out of place. She has not granted anything, the free use of the Canal by vessels of all nations having been the condition under which Great Britain consented to the abrogation of the Clayton-Bulwer Treaty and to the stipulation of Article II of the Hay-Pauncefote Treaty according to which--in contradistinction to Article I of the Clayton-Bulwer Treaty--the United States is allowed to have a canal constructed under her auspices.
