While you may be right, 14 and 28 years (with extension) are currently unrealistic goals due to international obligations [0]. However, I believe returning to the terms of the 1976 act (75 years or life plus 50 years) would be imminently achievable with good political maneuvering.

Thinking this was a hot-button issue on HN, I submitted a post advocating for a coordinated political effort a few weeks ago [1], but it didn't get any traction. However, seeing comments like this gives me hope.
