Much of the eastern United States has recently been affected by smoke originating from massive wildfires in Canada. It's a genuine problem. But Trump's threat to impose new tariffs on Canadian goods in response won't make the situation any better. If implemented, it would damage both the US and Canadian economies, and further poison relations between the two countries. And it has no chance of actually alleviating the wildfire problem. Furthermore, no law authorizes the president to impose tariffs in response to natural disasters like this one.
Trump claims the tariffs are justified because "[w]e are holding Canada responsible for the fact that they are not properly maintaining their Forests, and Brush therein, and the United States is being unnecessarily invaded by filthy, polluted, and unhealthy air." But, in reality, the fires are caused by a combination of lightning, weather patterns, and global warming. They cannot be fixed by improvement "forest management."
