Also, there are the timelines. The administration says it wants to move quickly. It's 300 days statutorily under TPA: 90 days here, 60 days there, 150 days there, 75 days there. You can project this with the U.S. mid-term elections and the Mexican presidential elections, which are hugely important. You get the scenario that it's going to be years at best until we can come out. These are deadlines the administration can't move, only Congress can move, and Congress has shown no willingness to move them.
