 Isthmian patriots particularly resented the haste with which Bunau-Varilla concluded the treaty, an effort partially designed to preclude any objections an arriving Panamanian delegation might raise.Nonetheless, the Panamanians, having no apparent alternative, ratified the treaty on December 2, and approval by the United States Senate came on February 23, 1904.The rights granted to the United States in the so-called Hay–Bunau-Varilla Treaty were extensive.
