Tuhia he haere tonu mo tenei whitianga - I whakaaro a Roosevelt ki te hanga i te awa ahakoa, ma te whakamahi i tetahi kirimana o mua me Colombia i hoatu ai ki te US nga tika whakawhiti mo te Raina Raina o Panama. I matapae a Hay "he tutu i runga i te Isthmus [o Panama] ki taua kawanatanga o te wairangi me te koretake... i Bogotá". I hui tahi a Bunau-Varilla me nga tangata e rua, a i whakapumau ki a raatau kei te haere mai te hurihanga, me te kawanatanga Panamanian he pai ake ki te awa. I te Oketopa, ka whakahau a Roosevelt kia whakatūhia ngā kaipuke Navy ki te taha o Panama. Ko nga Panamanians i whakakeke i te timatanga o Noema 1903, me te whakauru a Colombia i aukatihia e te noho o nga hoia o Amerika. Na te whakaritenga i mua, i tohua a Bunau-Varilla hei māngai mo te iwi hou i Washington, a, i tere te whakawhitiwhiti korero mo te Tiriti o Hay <unk>Bunau-Varilla, i hainatia i te Noema 18, e hoatu ana ki te United States te tika ki te hanga i te awa i roto i te rohe
whānui, ka whai mana tonu a U.S. ki runga. Kaore tenei i pai ki nga kaitohutohu Panamanian i tae mai ki Washington i muri tata mai i te hainatanga, engari kaore i maia ki te whakarere. I whakaaetia te tiriti e nga iwi e rua, a ka tīmata te mahi i te Canal Panama i te tau 1904. I tuhituhi a Hay ki te Hekeretari o te Pakanga a Elihu Root, e whakamoemiti ana ki "te huarahi tino tika i whaihia e te Perehitini" he mea pai ake ki te mahi patu o te isthmus.
