Thank you, Alex.

This is quite true.
For practical part I might add this:
1. One reason is that the controlled chain reaction during fission is capable of giving energy from U233, U235 (occurs naturally), Pu239, Pu241.
If there is no chain reaction during fission, it would be necessary to provide a thermal neutron for each nuclear reaction "manually".
2. Fission gives much more energy than one reaction of fusion, but the fusion is more efficient per kilogramme of matter.
3.
Weizsäckers formula about binding energies in nuclei may help understanding the calculations.
