Any similarity between NIF and a practical Fusion Reactor is purely accidental.

Congress opted instead to fund it as a weapons-related program, but that doesn't mean that's all they're doing, and for a while they were explicitly spending the majority of their efforts on achieving energy gain. Recently they missed a deadline set by Congress which redirected the program to be only 20% for energy.
A really great history of the U.S. fusion program, from the 1950s to about 2012, is Search for the Ultimate Energy Source by Stephen O. Dean, who was deeply involved with much of it. http://www.amazon.com/Search-Ultimate-Energy-Source-ebook/dp...
Can you back this statement up?
But I should probably say "many" rather than "most," since he didn't give actual numbers.
You challenged the idea that a DoD project is indeed defense-related by citing (but not really) an obscure book that maybe says some scientists involved with NIF really believe it's for energy production. Forgive me if I'm not convinced.
Second, if anyone would like to see an inspirational speech given by NIF Director Ed Moses on how you move from theory to a a working reactor based on this technology, he spoke at Long Now in SF a few years ago:

TL;DR - More money -> likely fewer results.
Large organizations tend toward waste, delay and mediocrity. Without a profit motive and a mission to deliver a specific solution, the modus operandi is to grow as big of a budget pyramid as possible while providing just enough press releases to keep the DOE gravy-train rolling.
This is why high beta and other approaches from smaller groups may likely crack the problem, despite not having all of the toys (and distractions).
I have seen 9 figure / 7 year internal projects silently scuttled as to not create a "failure", despite delivering nothing. I have seen 6 figure projects surpass 8 figure projects through a combination of talent and leadership. I've seen duplication of systems merely because two depts can't find a way to work together, effectively doubling costs.
Depends on the meaning of "success." "Success" of a political project is rarely based on results; all projects are "successful," because the unsuccessful ones disappear. Real success, as in achieving an novel aim, is another matter.
Success is great, but at too high of a cost, it may make the results bitter (bodies in the Great Wall, pushing $10 billion total spent on NIF without results). This is where private R&D excels: there's a defined goal, time/cost pressures and usually fewer political constraints. This is why high beta has a higher probability of success AND a lower cost of success (better value/$).
What do you think is reasonable price tag for the development of an entirely new form of clean energy?
Saturn V might have worked, but justifying costs of one program with historic waste of another is still an invalid argument in the context of cost of success.
