On the SPP, I have less to say. Those who say it's dead are probably right.
On folding the side agreements into NAFTA, I think that's something that may well be attractive to the United States. As a candidate, Obama talked rather boldly about changes to NAFTA. Obviously that is unlikely to happen. But rolling the side agreements into NAFTA looks like a change to NAFTA. Remember, we got the side agreements because President Clinton wanted some window dressing to justify the fact that he had opposed NAFTA and now was actually agreeing to it. This would be history repeating itself, to some extent.
The question is whether something worthwhile would come out of it. Folding it into NAFTA, we'd be doing what? Would we be keeping the same provisions, so that we can have complaints being made and the governments narrowing it down and nothing much coming out of it, or moving it into something more substantive, so that the issues of labour and the environment aren't taken seriously in the NAFTA agreement? That's a big challenge, but I think it's a worthwhile challenge.
