The problem with NAFTA, before we renegotiated it as CUSMA, was that it went 26-some-odd years without ever being updated. In the interim years, the Internet became a thing. We want to avoid that situation.
The problem I see with sunset clauses is that it's sort of a shotgun approach to it, rather than just healthy reviews and agreeing to review, without falling off a cliff as the cost of not doing it. As long as that is avoided in any sort of negotiation, I think that's important. You don't want to have that disconnect or a discontinuity to happen in coverage of the agreement while we're negotiating.
