They *do* get considerable D-T fusion with the FCG in the paper listed
below. They just don't use a secondary magnetic pusher to generate a
large fusion yield.

What's most interesting (and potentially scary) is the whole field of
use for this 4th generation stuff: "microyield" fusion explosives of
10-100 tons TNT yield, which are relatively clean in terms of fallout.
Bunker busters, if you will. Or really big excavation charges. These
have never existed before.

China was planning to use (3rd generation, fission triggered
thermonuclear) nukes for excavating a new channel for the Yangtze River
at one point (the nukes would have been used to dismantle a mountain, I

The US did tests with synchronized small nuke explosions for this
purpose (actually oil field production stimulation), but abandoned the
concept as being too dirty. This work could change that picture.
