Will Trump’s War With Canada Become Global?

The article argues that US President Donald Trump's demand for compensation from Canada for transboundary wildfire smoke marks a historic shift. For the first time, a great power has unilaterally priced climate-driven harms and sought compensation, turning a development/insurance issue into a security and trade dispute between two G7 economies. The author notes the irony that Canadian PM Mark Carney, a former central banker who warned about climate financial risks, now faces pressure to expand fossil fuel production. The piece warns this sets a precedent for other transboundary climate harms like smoke, floodwaters, and drought-driven migration, potentially leading to more international climate-security conflicts.
