With Trump floating aggressive desires to acquire foreign territories like the Panama Canal, Greenland, and Canada, ambassador confirmations could get messy.

Trump again having designs on Greenland comes after the president-elect suggested over the weekend that the U.S. could retake control of the Panama Canal if something isn't done to ease rising shipping costs required for using the waterway linking the Atlantic and Pacific oceans.

Experts say Trump's provocative social media posts on Christmas Day about foreign policy opens the door for new alliances and new thinking to counter China's growing influence.
