Icebreakers are essential for navigating Greenland's icy seas, but the U.S. faces a challenge with its limited fleet. The U.S. has only three, with one barely functional. The country has agreements to acquire 11 more, but must rely on adversaries like China and Russia — or allies like Canada and Finland, both of whom have recently weathered blistering criticism and threats of tariffs by Trump over Greenland. Finland is a leader in icebreaker technology and has built most of the world's fleet. Cooperation with allies is vital, as the U.S. can't achieve this alone.
