Tariffs have recently been the subject of much debate. Some argue that imposing tariffs runs the risk of starting trade wars and ultimately harming the economy. Others argue that tariffs are a means to an end, forcing countries and their respective governments to address these issues head on and bringing about positive change. 

Questions

1. Why are tariffs sometimes seen as a retaliatory measure? 

2. Who is right? Can tariffs really bring about change or do they create negative political tension?
