If you believe, as I do, that there is no alternative to (re)privatizing the twins, there has to be a recap/release, and for a recap/release to occur, settling of all remaining litigation is a sine qua non.
That is why, after all, there is a clause in the 4th Letter Agreement that recap/release cannot take place until the amount in dispute of all remaining litigation has been reduced to below $5 billion.
The government will not settle. The lawyers will milk this until the bitter end.
