I can make a general comment and maybe Fiona can add to it. As a trading nation, I think we're the most dependent on trade of any OECD country, so obviously protectionism doesn't help us.
Our association supported free trade, in 1982, I think it was, so we were way ahead of the curve, on the grounds that you can't build billion-dollar chemical plants for a domestic market of what was probably 28 million people at the time. It's a globally traded commodity. You have to build plants to export and to import. That's basically how the industry works.
So on protectionism, we of course support Mr. Harper's strong comments, and I was very happy to see President Obama kind of shift his view on the NAFTA renegotiation as well. Yes, trade is critical to us. Just to add to that, just so you understand our business, a lot of that trade is intra-company trade, whereby part of a company is sending a product to another part of another plant in the United States to complete a process, which is much like what we've heard with the auto industry and the moving back and forth. It is so highly integrated that the idea of putting up barriers would be just a complete disaster.
Jay made some interesting comments on that yesterday about all the various things that are happening that can create barriers, but I don't think, Fiona, that we've seen those kinds of barriers, because we're producing tank cars of chemicals. It's a little bit different, perhaps, from steel for bridges.
