The short answer is yes, but it does need political consensus worldwide. That hasn't been the case, as everyone knows, in the last decade, including the ministers when meeting the president at the WTO ministerial meeting in Bali, Indonesia, not coming up with very much. There really isn't the political will to advance the WTO, to give you a very short answer.
A lot of international trade is behaviour rather than law. I say this as an economist, not as a lawyer. With the Americans at times, both in defence procurement and in the example you mentioned in agriculture, the clerk on down in the hierarchy can do some very strange things at times, including what you've just reported on. To some extent, that's behaviour. As the other side, you have to keep at them and say, “You've got to play the game the way we understood it to be played and the way you like others to play it.” That's why I don't worry if the Chinese take on the Americans from time to time. It doesn't hurt for them to get their own medicine.
Getting back to the diversification question, that's why we need to have allies over and above the United States. The United States is number one in terms of us, but we have to work with others to keep pressure on them at every level of their government and their private sector to make it in their interest to behave properly, frankly.
