Recent trade negotiations between Canada and the United States have ended in a calamitous collapse. Observers suggest this breakdown serves as a stark warning to other nations worldwide. The failure indicates that pursuing fair deals with the current US administration may be futile from the start. According to political science experts, Washington is now prioritizing its own interests over shared economic ground. This shift persists regardless of the deep historical relationship between the two neighboring countries. The current administration has signaled a departure from global economic coordination and harmony. Consequently, the episode highlights a growing trend of unilateralism in American foreign policy.
