Canada cannot win a trade war with the US. When we are on our knees he’s going to ask for Yukon, nwt and nunavut. Saying basically nobody lives there and we don’t need it. He can easily buy out northern Canadians by offering lots of money or citizenship and the other 39 million Canadians will reluctantly agree it’s the best compromise.
He knows climate change is real and it makes the north more and more viable every day due to its resources and shipping route.
Another obvious hint at this was traitor Danielle Smith suggesting US military bases in the north just last week.
The U.S. has a ton of offshore oil reserves - to my understanding the preservation of these sites is less about the environment and more about strategic planning.
This will just result in the Gulf of Mexico becoming more of a toxic dump.
