re: Canada has a larger supply of softwood lumber, and hence sell for a lower price, basic economics, Americans can't compete (or handle that fact either)
Seriously without the always fun Great White North bashing, the US is wrong to impose the trade tarrifs on the lumber. Sadly, both US parties have recently diverted away from free trade.
I do not wish to provoke another war with Canader as the last time we suffered a vicious beating. I can just see a quagmire of US forces bogged down in intractable beaver swamps, treacherous tundra and deep snow.
