Former President Donald Trump's recent statements about potentially reclaiming the Panama Canal, annexing Greenland, and turning Canada into a U.S. state have triggered international concern and debate. These assertions, shared on social media, raise questions about his foreign policy approach and have been met with strong rebuttals from the nations involved.

Trump alleges that U.S. shipping companies face exorbitant fees to use the Panama Canal and suggests undue Chinese influence over the waterway. Panamanian officials firmly deny these claims, emphasizing their nation's sovereignty and independence. President José Raúl Mulino stated unequivocally that the canal's operations are free from external control.

Regarding Canada, Trump proposed its integration as the 51st U.S. state, claiming it would lead to significant tax cuts, business growth, and enhanced military protection. Canadian Prime Minister Justin Trudeau has not formally responded to these renewed suggestions.

Trump also reiterated his interest in Greenland, citing its strategic importance and natural resources. Greenland's Prime Minister Mute Egede promptly dismissed the idea of selling the territory, emphasizing Greenland's self-determination.

Increased shipping costs through the Panama Canal are attributed to factors like drought-induced low water levels and heightened global shipping competition. These issues have led to vessel traffic limitations and toll increases. Other factors, such as disruptions in the Red Sea, have further impacted shipping routes and costs.

These renewed pronouncements from Trump diverge from his previous "America First" policy focus and have raised questions about the potential direction of U.S. foreign policy. While some, like Rep. Ryan Zinke, share Trump's concerns about Chinese influence in the Panama Canal region, others view his statements with apprehension.
