And just because it can and I believe will, be used in weapons systems, does not imply I think it will make war more likely, or more dangerous. Or that FF is “Bad” or should be avoided.

I agree that reducing the importance of oil and providing cheaper, more abundant energy will GREATLY reduce world tensions. And reductions in poverty that would be a “byproduct” of FF will also make for a more peaceful and less violent world.

These are all good things.

But we are a long way from a “Star Trek” utopia and military force is a fact of life. And this is not always just the military force used by legitimate governments. Even tiny groups (Oklahoma City bomber) can use force.
