What were Trump's goals for American territorial expansion and how did he propose to achieve them?

During a press conference at Mar-a-Lago in early January, Donald Trump explicitly outlined his territorial expansion goals, claiming the Panama Canal should never have been ceded to Panama, alleging without evidence that it was operated by China and needed for American economic security. He also expressed interest in acquiring Greenland for national security purposes, questioning Denmark's legal right to the territory. Trump threatened to impose high-level tariffs on Denmark if they refused to cooperate in relinquishing Greenland. When pressed by a reporter, he notably refused to rule out using the US Military to acquire either Greenland or the Panama Canal, suggesting he was willing to consider forceful measures if diplomatic or economic pressure failed to achieve his territorial ambitions.
